jquery ui的css框架...

jQuery UI的CSS框架设计得非常鲁棒方便用于定制用户界面控件。框架包括很多适合多数用户界面需要的CSS类，这些类能用jQuery UI ThemeRoller来所见即所得地修改。如果你的控件也采用本框架，你的控件就可以和社区的其它大量控件或者代码更容易地集成。

框架类

The following CSS classes are split between ui.core.css and ui.theme.css, depending on whether styles are fixed and structural, or themeable (colors, fonts, backgrounds, etc) respectively. These classes are designed to be applied to User Interface elements to achieve visual consistency across an application and allow components to be themeable by jQuery UI ThemeRoller.

• .ui-helper-hidden-accessible: 将位置设置到屏幕之外让元素看不见(但不是display:none)

Icons图标

States and images状态和图片

• .ui-icon: 图标元素的基本类Base class to be applied to an icon element. Sets dimensions to 16px square block, hides inner text, sets background image to "content" state sprite image. Note: .ui-icon class will be given a different sprite background image depending on its parent container. For example, a ui-icon element within a ui-state-default container will get colored according to the ui-state-default's icon color.

Icon types

After declaring a ".ui-icon" class, you can follow up with a second class describing the type of icon you'd like. Icon classes generally follow a syntax of .ui-icon-{icon type}-{icon sub description}-{direction}.

For example, a single triangle icon pointing to the right looks like this: .ui-icon-triangle-1-e

jQuery UI's ThemeRoller provides the full set of CSS framework icons in its preview column. Hover over them to see the class name.
