Layout 2.1 implementation

This article needs a technical review. How you can help.

This article gives you all you need to implement a v2.1 Layout structure in your own app.

Live sample

The following gives you an idea of what the rendered layout would look like, and how it would work (the vertical scroll bar would not appear on the actual device.)

Code

Here is the code you'll need.

CSS

<link href="(your styles folder)/style/layout.css" rel="stylesheet" type="text/css">

The CSS can be found in the Gaia project 2.1 branch under shared/style/layout.css. Feel free to copy this into your own project, or just link to the version found in the Gaia project if you don't intend modifying it and are just intending your app to be installed on Firefox OS.

After attaching layout.css to your page, you need to use display: flex in your main container and the classes fit and scroll in your content section.

HTML

Note: The CSS inside the <style> element isn't needed for the implementation: it is just for the purposes of this example.
