The style and styleClass Attributes

The style and styleClass attributes allow you to specify 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 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 style sheet 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/.
