The style and styleClass Attributes

The style and styleClass attributes allow you to specify Cascading Style Sheets (CSS) styles for the rendered output of your tags. Displaying Error Messages With the h:message and h:messages Tags describes an example of using the style attribute to specify styles directly in the attribute. A component tag can instead refer to a CSS stylesheet class.

The following example shows the use of a dataTable tag that references the style class list-background:

<h:dataTable id="books"
    ...
    styleClass="list-background"
    value="#{bookDBAO.books}"
    var="book">

The stylesheet that defines this class is stylesheet.css, which will be included in the application. For more information on defining styles, see Cascading Style Sheets Specification at http://www.w3.org/Style/CSS/.
