7.css

A design system for building faithful recreations of old UIs.

Intro

7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css.

Hello, world!

This framework relies on the usage of semantic HTML. To make a button, you'll need to use a . Input elements require labels. Tabs rely on the role="tab" attribute. This page will guide you through that process, but accessibility is a primary goal of this project.

You can override many of the styles of your elements while maintaining the appearance provided by this framework. Need more padding on your buttons? Go for it. Need to add some color to your input labels? Be our guest.

This framework does not contain any JavaScript, it merely styles your HTML with some CSS. This means 7.css is compatible with your frontend framework of choice.

Installation / Usage

The fastest way to use 7.css is to import it from unpkg.

You can also install 7.css from npm.

Installation

npm install 7.css

Usage

import "7.css/dist/7.css";

Scoping

In case you need 7.css to coexist with another CSS/styling framework, you may use the 7.scoped.css stylesheet instead to scope the styling within a win7 class.

unpkg:

https://unpkg.com/7.css/dist/7.scoped.css

or npm:

import "7.css/dist/7.scoped.css"

Then in your code, wrap the component with .win7:

Show code

<div class="win7">
  <button>A Win7-styled buttonbutton>
div>

Also note that using the scoped stylesheet will eliminate the scrollbar styling as well.

Tree-shaking

In case you only need the styling of certain components rather than the complete stylesheet as a whole, you may import them separately as below:

unpkg:

https://unpkg.com/7.css/dist/gui/buttons.css
https://unpkg.com/7.css/dist/gui/tabs.css

or npm:

import "7.css/dist/gui/buttons.css"
import "7.css/dist/gui/tabs.css"

For more components, see the published gui folder.

Components

Balloon

A balloon is a small pop-up window that informs users of a non-critical problem or special condition in a control.

A balloon or tooltip can be created using the role="tooltip" attribute.

A balloon is better known as tooltip in web development.

Show code

<div role="tooltip">A balloon is better known as tooltip in web development.div>

A control may bind to a balloon with the aria-describedby attribute. You will need to set up an event for the control to trigger the balloon.

Press Backspace to dismiss

Show code

<input type="text" placeholder="Press Enter" aria-describedby="balloon-password" />
<div role="tooltip" id="balloon-password" hidden>Press Backspace to dismissdiv>

To change the position of the balloon, which subsequently change the placement of its tail, combine the respective vertical and horizontal classes:

• Vertical: .is-top / .is-bottom
• Horizontal: .is-left / .is-right

This balloon is positioned bottom right of the source control (default behavior).

This balloon is positioned bottom left of the source control.

This balloon is positioned top left of the source control.

This balloon is positioned top right of the source control.

Show code

<div role="tooltip">This balloon is positioned bottom right of the source control (default behavior).div>
<div role="tooltip" class="is-bottom is-left">This balloon is positioned bottom left of the source control.div>
<div role="tooltip" class="is-top is-left">This balloon is positioned top left of the source control.div>
<div role="tooltip" class="is-top is-right">This balloon is positioned top right of the source control.div>

Button

A command button, also referred to as a push button, is a control that causes the application to perform some action when the user clicks it.

A standard button measures 75px wide and 23px tall with 12px of horizontal padding by default. They are styled with 2 shades of gray as a vertical gradient.

Show code

<button>Click mebutton>

When buttons are clicked, the gray gradient is shifted to corresponding sky blues. The following button is simulated to be in the pressed (active) state.

Show code

<button>I am being pressedbutton>

Disabled buttons have solid background and lighter border.

Show code

<button disabled>I cannot be clickedbutton>

Button focus is communicated with a dotted border, set 4px within the contents of the button. The following example is simulated to be focused.

Show code

<button>I am focusedbutton>

A default button (in Windows, hitting the Enter key in a dialog context triggers the button) has a greenish-blue border and a light blue gradient shade.

Show code

<button class="default">I am the one!button>

The button styles are also applied to the file input element. Due to the complex setup, the styles of the standard button's states (hover, active, focus etc.) cannot be applied to the file input button.

Show code

<input type="file" />

You can use the below workaround to apply the complete button styles to a file input element. In this setup, the file input is hidden and a label with the role="button" attribute is used to trigger the file selection dialog. The tabindex="0" attribute ensures the button is keyboard accessible. Some JavaScript is required if you want the label to trigger when it is focused and activated with the keyboard.

Show code

<label role="button" tabindex="0"><input type="file" /> Choose filelabel>
<label role="button" tabindex="0" class="default"><input type="file" /> Browse...label>

CheckBox

A check box represents an independent or non-exclusive choice.

Checkboxes are represented with a sunken panel, populated with a "check" icon when selected, next to a label indicating the choice.

Note: You must include a corresponding label after your checkbox, using the element with a for attribute pointed at the id of your input. This ensures the checkbox is easy to use with assistive technologies, on top of ensuring a good user experience for all (navigating with the tab key, being able to click the entire label to select the box). This is a checkbox

Show code

<input type="checkbox" id="example1">
<label for="example1">This is a checkboxlabel>

Checkboxes can be selected and disabled with the standard checked and disabled attributes. I am checked I am inactive I am inactive but still checked

Show code

<div class="group">
  <div>
    <input checked type="checkbox" id="example2">
    <label for="example2">I am checkedlabel>
  div>
  <div>
    <input disabled type="checkbox" id="example3">
    <label for="example3">I am inactivelabel>
  div>
  <div>
    <input checked disabled type="checkbox" id="example4">
    <label for="example4">I am inactive but still checkedlabel>
  div>
div>

Collapse

Users can show or hide additional information including data, options, or commands.

A collapsible section can be created using the elements details and summary.

Expand me to see something interesting

🎉 Tadah!

Show code

<details>
  <summary>Expand me to see something interestingsummary>
  <p>🎉 Tadah!p>
details>

Add an open attribute to expand the content by default.

I open myself willingly

• This is my family
• This is my house
• This is my car

Show code

<details open>
  <summary>I open myself willinglysummary>
  <ul>
    <li>This is my familyli>
    <li>This is my houseli>
    <li>This is my carli>
  ul>
details>

Combobox

A combo box is a combination of a standard list box or a drop-down list and an editable text box, thus allowing users to enter a value that isn't in the list.

To render a combo box, use a text input, a button, a parent ul, and children li together, wrapped inside a container element with the combobox class. For accessibility, follow the minimum requirements as below:

• Add a role="combobox" attribute to the text input
• Add a role="listbox" attribute to the ul
• Add a role="option" attribute to each li
• Specify the relationship between the list box and the text box by combining the id of the listbox with the aria-owns attribute on the text input

• Facebook
• Amazon
• Apple
• Netflix
• Google

Show code

<div class="combobox">
  <input type="text" role="combobox" aria-owns="company" />
  <button>button>
  <ul role="listbox" id="company">
    <li role="option">Facebookli>
    <li role="option">Amazonli>
    <li role="option">Appleli>
    <li role="option">Netflixli>
    <li role="option">Googleli>
  ul>
div>

For more options of the list box, see the ListBox section.

Dropdown

A drop-down list box allows the selection of only a single item from a list. In its closed state, the control displays the current value for the control. The user opens the list to change the value.

Dropdowns can be rendered by using the select and option elements. 5 - Incredible! 4 - Great! 3 - Pretty good 2 - Not so great 1 - Unfortunate

Show code

<select>
  <option>5 - Incredible!option>
  <option>4 - Great!option>
  <option>3 - Pretty goodoption>
  <option>2 - Not so greatoption>
  <option>1 - Unfortunateoption>
select>

By default, the first option will be selected. You can change this by giving one of your option elements the selected attribute. 5 - Incredible! 4 - Great! 3 - Pretty good 2 - Not so great 1 - Unfortunate

Show code

<select>
  <option>5 - Incredible!option>
  <option>4 - Great!option>
  <option selected>3 - Pretty goodoption>
  <option>2 - Not so greatoption>
  <option>1 - Unfortunateoption>
select>

Disabled dropdown. 0 - Dropdown disabled

Show code

<select disabled>
  <option>0 - Dropdown disabledoption>
select>

GroupBox

A group box is a special control you can use to organize a set of controls. A group box is a rectangular frame with an optional label that surrounds a set of controls.

A group box can be used by wrapping your elements with the fieldset tag. It contains a sunken outer border and a raised inner border, resembling an engraved box around your controls.

Select one:

Diners Drive-Ins Dives

Show code

<fieldset>
  <div>Select one:div>
  <div>
    <input id="radio5" type="radio" name="fieldset-example">
    <label for="radio5">Dinerslabel>
  div>
  <div>
    <input id="radio6" type="radio" name="fieldset-example">
    <label for="radio6">Drive-Inslabel>
  div>
  <div>
    <input id="radio7" type="radio" name="fieldset-example">
    <label for="radio7">Diveslabel>
  div>
fieldset>

You can provide your group with a label by placing a legend element within the fieldset.

Today's mood

Claire Saffitz Brad Leone Chris Morocco Carla Lalli Music

Show code

<fieldset>
  <legend>Today's moodlegend>
  <div>
    <input id="radio8" type="radio" name="fieldset-example2">
    <label for="radio8">Claire Saffitzlabel>
  div>
  <div>
    <input id="radio9" type="radio" name="fieldset-example2">
    <label for="radio9">Brad Leonelabel>
  div>
  <div>
    <input id="radio10" type="radio" name="fieldset-example2">
    <label for="radio10">Chris Moroccolabel>
  div>
  <div>
    <input id="radio11" type="radio" name="fieldset-example2">
    <label for="radio11">Carla Lalli Musiclabel>
  div>
fieldset>

There is a handy group utility class provided out of the box which can be used to group elements without the need for a fieldset, and ensure a consistent spacing between them. I am checked I am inactive I am inactive but still checked

Show code

<div class="group">
  <div>
    <input checked type="checkbox" id="example12">
    <label for="example12">I am checkedlabel>
  div>
  <div>
    <input disabled type="checkbox" id="example13">
    <label for="example13">I am inactivelabel>
  div>
  <div>
    <input checked disabled type="checkbox" id="example14">
    <label for="example14">I am inactive but still checkedlabel>
  div>
div>

ListBox

With a list box, users can select from a set of values presented in a list that is always visible.

There are 2 ways you can render a list box. The simple one is using the select element with a multiple attribute specified. 5 - Incredible! 4 - Great! 3 - Pretty good 2 - Not so great 1 - Unfortunate

Show code

<select multiple>
  <option>5 - Incredible!option>
  <option selected>4 - Great!option>
  <option>3 - Pretty goodoption>
  <option>2 - Not so greatoption>
  <option>1 - Unfortunateoption>
select>

The complex one is using a combination of the ul/li elements with the role attributes.

• Facebook
• Amazon
• Apple
• Netflix
• Google

Show code

<ul role="listbox">
  <li role="option">Facebookli>
  <li role="option" aria-selected="true">Amazonli>
  <li role="option">Appleli>
  <li role="option">Netflixli>
  <li role="option">Googleli>
ul>

The latter offers more flexibility over using a mere select element. Choose the one that is more appropriate depending on your context or use case.

To add a drop shadow to the list box, use the has-shadow class. To add a hovering style on the list box items (using role attribute only), use the has-hover class.

• Facebook
• Amazon
• Apple
• Netflix
• Google

Show code

<ul role="listbox" class="has-shadow has-hover">
  <li role="option">Facebookli>
  <li role="option">Amazonli>
  <li role="option">Appleli>
  <li role="option">Netflixli>
  <li role="option">Googleli>
ul>

ListView (table)

With a list view, users can view and interact with a collection of data objects, using either single selection or multiple selection.

Currently, the ListView is only implemented as the Details view, which styles tables.

Here's another example showcasing advanced usage, for example:

• The handling of long text (using the width property of the table to limit the width)
• Using the has-shadow class to add a shadow to the table
• Flipping the column header sort indicator by adding the up class
• Changing text alignment using the text-align property
• The highlighted column header style without sort indicator (I didn't want to add another table just for that)

Navigation

The following components compose a complete navigation menu, also known as Navbar.

Menu

Menus are hierarchical lists of commands or options available to users in the current context.

A menu can be rendered using a composition of a parent ul and child items li, role="menu" and role="menuitem" attributes must be specified on the ul and li respectively.

If a menu item has a submenu, add an aria-haspopup="true" attribute to it to render a caret indicator.

To make the menu focusable, specify the tabindex attributes on the items. Alternatively, you can use an a to achieve the same.

  <li role="menuitem"><a href="#menu">Gadgetsa>li>
  <li role="menuitem"><a href="#menu">Personalizea>li>
ul>

By default, the submenu is only shown when the linked item is focused/clicked. To add the hovering/mouse-over trigger, you can add a can-hover class to the root container.

Use a has-divider class to make a horizontal line after the menu item. Disable a menu item by placing an aria-disabled attribute on it.

You may associate a menu item with an icon by using the img element. (Icons provided by Icons8)

To render menu items that are options with bullets and checkmarks, use the corresponding input type (radio or checkbox).

• Large icons
• Medium icons
• Small icons
• Auto arrange icons
• Align icons to grid

MenuBar

A menu bar is a list of labeled menu categories typically located near the top of a window.

A menu bar can be created in a similar manner to the menu, however, use a role="menubar" attribute in place of role="menu".

  <li role="menuitem" tabindex="0">Editli>

  <li role="menuitem" tabindex="0">Helpli>
ul>

Combining it with the Menu component, we will have a complete menu bar with the associated menu dropdowns.

To accommodate an extra piece of info for a menu item (like a shortcut mnemonic) on the right side, nest it with an span element.

OptionButton

An option button, also referred to as a radio button, represents a single choice within a limited set of mutually exclusive choices. That is, the user can choose only one set of options.

Option buttons can be used via the radio type on an input element.

Option buttons can be grouped by specifying a shared name attribute on each input. Yes No

Show code

<div style="display: flex; flex-direction: column; gap: 6px">
  <div>
    <input id="radio20" type="radio" name="first-example">
    <label for="radio20">Yeslabel>
  div>
  <div>
    <input id="radio21" type="radio" name="first-example">
    <label for="radio21">Nolabel>
  div>
div>

Option buttons can also be checked and disabled with their corresponding HTML attributes. Peanut butter should be smooth I understand why people like crunchy peanut butter Crunchy peanut butter is good

Show code

<div style="display: flex; flex-direction: column; gap: 6px">
  <div>
    <input id="radio22" type="radio" name="second-example">

ProgressBar

A common control that displays the progress of a particular operation as a graphical bar.

Progress bars can be created with a div using role="progressbar", and another nested div is required to make the inner bar.

Specify the width of the inner bar to indicate the progress.

For accessibility, you might want to specify the respective aria-* attributes. Refer to MDN for more information.

Show code

<div role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="80">
  <div style="width: 80%">div>
div>

To indicate the progress bar in paused state, add a paused class.

Show code

<div role="progressbar" class="paused">
  <div style="width: 50%">div>
div>

To indicate the progress bar in error state, add an error class.

Show code

<div role="progressbar" class="error">
  <div style="width: 30%">div>
div>

To animate the progress bar, add an animate class.

Show code

<div role="progressbar" class="animate">
  <div style="width: 60%">div>
div>

To create an indeterminate progress bar, add a marquee class and remove the nested div.

Show code

<div role="progressbar" class="marquee">div>

Scrollbar

A control that allows users to scroll the content of a window, either vertically or horizontally.

To override the browser scrollbar's system styling for a particular section, add a has-scrollbar class to the container element.

Note that this only works with WebKit-based browsers.

SearchBox

With a Search box, users can quickly locate specific objects or text within a large set of data by filtering or highlighting matches.

There are 2 variants of the search box available.

An instant search, where the results are displayed immediately as the user types, can be rendered just by specifying a type="search" attribute on an input element:

Show code

<input type="search" placeholder="Search" />

A regular search, where a search is performed when the user clicks the search button, requires a search input and a button wrapped inside a container a container element with the class searchbox.

Show code

<div class="searchbox">
  <input type="search" placeholder="Search" />
  <button aria-label="search">button>
div>

Slider

A slider, sometimes called a trackbar control, consists of a bar that defines the extent or range of the adjustment and an indicator that shows the current value for the control...

Sliders can rendered by specifying a range type on an input element. Volume: Low High

Show code

<div style="max-width: 300px; display: flex; align-items: center; gap: 0.5rem">
  <label>Volume:label>
  <label>Lowlabel>
  <input type="range" min="1" max="11" value="5" />
  <label>Highlabel>
div>

You can make use of the has-box-indicator class replace the default indicator with a box indicator, furthermore the slider can be wrapped with a div using is-vertical to display the input vertically.

Note: To change the length of a vertical slider, the input width and div height. Cowbell

Show code

<div style="display: flex; align-items: center; gap: 0.5rem">
  <label>Cowbelllabel>
  <div class="is-vertical">
    <input class="has-box-indicator" type="range" min="1" max="3" step="1" value="2" />
  div>
div>

Spinner

A spinner or loader, also referred as ProgressRing, is a type of progress control to indicate that an operation is underway and its completion time is unknown.

To render a spinner element, use either a spinner or a loader class. To animate the spinner, add an animate class.

For accessibility, we use an aria-label attribute with a desired text to inform assistive technologies about the presence of the spinner.

Show code

<span class="spinner" aria-label="Spinning">span>
<span class="loader" aria-label="Loading">span>
<span class="loader animate" aria-label="Processing your request">span>

Tabs

Tabs provide a way to present related information on separate labeled pages.

Creating tabs

To create a tab, use a menu element with role="tablist". Then for the tab titles, use a button with role="tab", and set the aria-controls attribute to the corresponding id of the element with role="tabpanel".

TextBox

A text box (also referred to as an edit control) is a rectangular control where the user enters or edits text. It can be defined to support a single line or multiple lines of text.

Text boxes can be rendered by specifying a text type on an input element. As with checkboxes and radio buttons, you should provide a corresponding label with a properly set for attribute. Occupation

Show code

<label for="text29">Occupationlabel>
<input id="text29" type="text" />

Additionally, you can make use of the group class to position your label above the input instead of beside it. Address (Line 1) Address (Line 2)

Show code

<div class="group" style="width: 200px">
  <label for="text30">Address (Line 1)label>
  <input id="text30" type="text" />
div>
<div class="group" style="width: 200px">
  <label for="text31">Address (Line 2)label>
  <input id="text31" type="text" />
div>

To support multiple lines in the user's input, use the textarea element instead. Additional notes

Show code

<div class="group" style="width: 200px">
  <label for="text32">Additional noteslabel>
  <textarea id="text32" rows="8">textarea>
div>

TreeView

A tree view control is a special list box control that displays a set of objects as an indented outline based on their logical hierarchical relationship.

To render a tree view, use an ul element with the tree-view class. The children of this list (li elements), can contain whatever you'd like.

• We can put
• ✨ Whatever ✨
• We want in here

Show code

<ul class="tree-view has-container">
  <li>We can putli>
  <li><strong style="color: purple">✨ Whatever ✨strong>li>
  <li>We want in hereli>
ul>

To make this a tree, we can nest further ul elements (no class needed on these). This will provide them with indentation to illustrate the hierarchical relations of the tree.

To create collapsible sections, wrap child lists inside details elements.

Window

The following components illustrate how to build complete windows using 7.css.

Title Bar

At the top edge of the window, inside its border, is the title bar (also reffered to as the caption or caption bar), which extends across the width of the window. The title bar identifies the contents of the window.

Include command buttons associated with the common commands of the primary window in the title bar. These buttons act as shortcuts to specific window commands.

You can build a complete title bar by making use of three classes, title-bar, title-bar-text, and title-bar-controls.

A Title Bar

Show code

<div class="title-bar">
  <div class="title-bar-text">A Title Bardiv>
  <div class="title-bar-controls">
    <button aria-label="Close">button>
  div>
div>

We make use of aria-label to render the Close button, to let assistive technologies know the intent of this button. You may also use "Minimize", "Maximize", "Restore" and "Help" like so:

A Title Bar

A maximized Title Bar

A help Title Bar

Show code

<div class="title-bar">
  <div class="title-bar-text">A Title Bardiv>
  <div class="title-bar-controls">
    <button aria-label="Minimize">button>
    <button aria-label="Maximize">button>
    <button aria-label="Close">button>
  div>
div>

<br>

<div class="title-bar">
  <div class="title-bar-text">A maximized Title Bardiv>
  <div class="title-bar-controls">
    <button aria-label="Minimize">button>
    <button aria-label="Restore">button>
    <button aria-label="Close">button>
  div>
div>

<br>

<div class="title-bar">
  <div class="title-bar-text">A help Title Bardiv>
  <div class="title-bar-controls">
    <button aria-label="Help">button>
    <button aria-label="Close">button>
  div>
div>

Alternatively, you can use the is-close, is-minimize, is-maximize, is-restore, is-help classes to target the respective controls for your styling preference.

To give our title bar a home, we wrap it in a window container. This provides a drop shadow to it. We can freely resize the window by specifying a width in the container style.

A complete window

Show code

<div class="window" style="max-width: 300px">
  <div class="title-bar">
    <div class="title-bar-text">A complete windowdiv>
    <div class="title-bar-controls">
      <button aria-label="Help">button>
      <button aria-label="Minimize">button>
      <button aria-label="Maximize">button>
      <button aria-label="Close">button>
    div>
  div>
div>

Place an active class either on the window container or the title bar itself to enable the active styles for the controls.

A complete window

Show code

<div class="window active" style="max-width: 300px">
  <div class="title-bar">
    <div class="title-bar-text">A complete windowdiv>
    <div class="title-bar-controls">
      <button aria-label="Help">button>
      <button aria-label="Minimize">button>
      <button aria-label="Maximize" disabled>button>
      <button aria-label="Close">button>
    div>
  div>
div>

Window body

Every window has a boundary that defines its shape.

To draw the contents of the window, we use the window-body class under the title bar. You may use the has-space class to add some padding to the window body.

A window with contents

There's so much room for activities!

Show code

<div class="window active" style="max-width: 300px">
  <div class="title-bar">
    <div class="title-bar-text">A window with contentsdiv>

Status Bar

A status bar is a special area within a window, typically the bottom, that displays information about the current state of what is being viewed in the window or any other contextual information, such as keyboard state.

You can render a status bar with the status-bar class, and status-bar-field for every child text element.

A Window With A Status Bar

There are just so many possibilities:

• A Task Manager
• A Notepad
• Or even a File Explorer!

Glass frame & Color

The glass window frames are a striking new aspect of the Microsoft Windows aesthetic, aiming to be both attractive and lightweight. These translucent frames give windows an open, less intrusive appearance, helping users focus on content and functionality rather than the interface surrounding it.

You can produce this "striking aspect" of the window with a glass class. The window frame then becomes translucent, the background is blurred behind the window.

The background behind is blurred.

If you want to override the default color of the window, you can redefine the --w7-w-bg variable as an inline value of the style attribute.

A violet window frame

You can change the window color just as simple.

To make the aero effect stick to the window when scrolling, or changing the viewport size, change the background-attachment property of the .title-bar to local or scroll (default is fixed), depending on your requirements.

Dialog Box

A dialog box is a secondary window that allows users to perform a command, asks users a question, or provides users with information or progress feedback.

Without JavaScript, a dialog box can be triggered by utilizing the URL fragment of an a element (denoted by the # sign), targeting a corresponding dialog box element with the matching id.

For accessibility, define the role="dialog" attribute on the element. Additionally, label the dialog using the aria-labelledby attribute, with the value pointing to the id of the title bar's text element. Open Dialog
