    Coding guide: Confirmations

    Download resources

    Here you can find examples of how to create confirmations 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 confirmations

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

    @import url(resources/confirm.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).

    Examples

    Note: Some desktop browsers will show a scroll bar in these examples; that doesn't happen on mobile devices.

    Simple confirmation box

    This code implements a simple confirmation box with a title and a body message.

    HTML

    <form role="dialog" data-type="confirm">
      <section>
        <h1>Confirmation</h1>
        <p>Are you sure you want to delete this contact?</p>
      </section>
      <menu>
        <button>Cancel</button>
        <button class="danger">Delete</button>
      </menu>
    </form>


    Firefox OS live demos generally require a Gecko-based browser, and work best in recent builds of Firefox.
