 ### Flexible styling and themes
 
-Widgets should provide hooks to enable developers to customize both behavioral and presentational aspects. Transition animations should be optional and customizable. Class names used on internal elements should be meaningful to jQuery UI users and enable styling either through [ThemeRoller](http://jqueryui.com/themeroller/) or hand-written CSS via the [jQuery UI CSS Framework](http://learn.jquery.com/jquery-ui/theming/). As much as possible, style attributes should be separated into the plugin's CSS, not within the scripts in order to make customization simple and clear. Widgets styles should be coded with proportional (em-based or % based) sizing and should re-flow horizontally to fill the space provided.
