Ext JS Themes
Ext JS comes with a handful of themes that make your rich web app look polished without lifting a finger. With three included themes to choose from, you can be sure your app looks fantastic in all major browsers.
Our new Themes Example in Ext JS 3.2+ makes it easy to test any theme or create your own. Applying your own custom theme is as simple as attaching your own stylesheet last. Structural and visual properties remain completely separated in Ext JS bundled themes, so colors and images can be easily modified to adhere to your project guidelines.
