Header 2.0 implementation

This article gives you all you need to implement a v2.0 Gaia-style Header in your own app.

Live sample

The following gives you an idea of what rendered headers would look like, and how they would operate.

Code

Here is the code you'll need.

CSS

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

The CSS can be found in the Gaia project 2.0 branch under shared/style/headers.css. Copy this into your own project, along with the associated resources.

HTML

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

<!doctype html>
