During the course of developing your Sencha Touch app, you will inevitably get around to theming…after all, while the default styles are nice, they don’t exactly scream individuality. Fortunately, Sencha Touch makes theming ridiculously easy, and there are a lot of resources available to help with getting started with that.

But let’s talk about a specific example. Let’s imagine that you want to simply change the background color on your app’s toolbars. The first thing you’ll probably do is pop open Firebug or Developer Tools to inspect the CSS that’s being applied to your toolbar. Unless you’ve already customized it, you’ll probably seem something like this:

I’ve highlighted “x-toolbar-dark”, because by default, the “UI” configuration option for Ext.Toolbar is set to “dark,” which applies the “x-toolbar-dark” class to your toolbar (it will apply “x-toolbar-light” if you specify “light” for ui…more on this later).

Here’s what the toolbar actually looks like:

If you inspect the properties of this CSS class, you should see something like this:

• background-color: #456F8D;
• background-image: -webkit-gradient(linear, 50% 0%, 50% 100%, color-stop(0%, #9cbacf), color-stop(2%, #5182a5), color-stop(100%, #395c75));
• background-image: -webkit-linear-gradient(#9cbacf,#5182a5 2%,#395c75);
• background-image: linear-gradient(#9cbacf,#5182a5 2%,#395c75);
• border-color: black;

Nothing too crazy here…just some background-image gradients to give the toolbar a nice textured feel. Now at this point, you might be tempted to do something crazy, something More >
