Coding guide: Buttons

Here you can find examples of how to create buttons on Firefox OS, as well as downloads for the CSS and image resources used by the built-in apps on Firefox OS. You can copy these resources into your app and make use of them to build apps that match these apps' appearances.

Implementing buttons

To implement a banner using the style shown here, place the CSS and media files into your app and then import the CSS using the @import at-rule:

@import url(resources/buttons.css);

Make sure the media files are in the location expected by the CSS (either by placing them in a corresponding location or by revising the CSS).

Example

HTML to create the buttons

The HTML below creates a number of buttons, showing different styles of them.

<h2 class="bb-docs">Normal</h2>
<div class="bb-docs">
  <button>Default</button>
  <button class="recommend">Recommend</button>
  <button class="danger">Danger</button>
 </div>
<h2 class="bb-docs">Disabled</h2>
<div class="bb-docs">
  <button disabled>Default</button>
  <a href="#" role="button" aria-disabled="true" class="recommend">Recommend</a>
  <button disabled class="danger">Danger</button>
</div>
<h2 class="bb-docs">Disabled with dark background</h2>
<div class="bb-docs dark">
  <button disabled>Default</button>
  <a href="#" role="button" aria-disabled="true" class="recommend">Recommend</a>
  <button disabled class="danger">Danger</button>
</div>
