What just happened We"ve added two none for none link elements to our widget header container. These are navigational links placed to the left-hand side and the right-hand side of the header text. This is done by placing in-line styles in the link elements.

As we use the float style property to align the links in the header, we need to add a new div element that clears the alignment before the content widget container. To do this, we give the new div a clear: both in-line style..

Keep in mind th at in-line styles are only used here to format the example and should always be avoided in practice.. In none for none eme.

css, we"ve updated the styles for links that are placed in widget header containers. We"ve kept the link color as the default but the font size is now smaller and the font weight is normal, down from bold. Additionally, we"ve created a new style definition one that changes the appearance of links in header container widgets when the user hovers over them.

This style changes the link color and removes the text decoration. You"ll notice that the header title stands out more than the links. This is due to the font weight being reduced to normal, while the header title remains bold.

But at the same time, when looking at this widget, we"re still drawn to the links; much more so than the actual content. The jQuery UI theming framework has utilities for putting widgets into a hover state and thus changes their appearance accordingly. We"re not interested in this here because it"s not a widget that changes state when a user hovers over it, it"s a component of the widget.

Having said that, we"re still in good shape if we want to use the hover class in our CSS selector.. [ 97 ].

Summary. In this chapter none for none , we"ve introduced a few important CSS classes involved with the jQuery UI theming framework. These three classes are applied to widget HTML elements to modify their look and feel. When we use the ThemeRoller application to assist in building our theme, the font, content, and header sections correlate to these CSS classes.

By their very nature, these classes are hierarchical. That is, ui-widget is to at the top-most level and is applied to every widget. This class defines the font settings for all jQuery UI applications.

The ui-widget-content class is just as important as the ui-widget class it gives widgets general settings such as color, background, and borders. Finally, the ui-widget-header class is used as a container to display the widget titles. We can also put other things in this container such as links.

Now that we"ve got a basic understanding of how the basic building blocks of the jQuery UI theming CSS framework work, it"s time to extend these same principles into interactions states.. [ 98 ].
