Working with Widget Containers generate, create upca none in software projects VB.NET This chapter covers GTIN - 12 for None widget containers. Widget containers have the biggest impact on your theme, so this is a good starting point for fine-grained theme changes. This is much more fine-grained than the ThemeRoller we saw in the previous chapter.

. In this chapter, we shall: Learn what widget containers are See how containers relate to widgets Explore the widget container CSS classes So let"s get on with it.. What are widget containers Every jQuery UI wid get has a container element. This is the outer-most element in the nested HTML elements that make up the widget. For instance, this might be a div element.

Inside the div, we find subordinate elements that give the widget its look and feel. Within the outer container element, widgets are sometimes further divided into sub-containers. Widgets can have header elements as well as main content elements.

What do widget containers have to do with themes Widget containers are used to apply the most general theme style properties to widgets. This includes things such as fonts, borders, and background colors. The container HTML elements are given container CSS classes from the jQuery UI theme framework.

. Working with Widget Containers Containers and widgets The following is an Software upc barcodes example of how the jQuery UI tabs widget uses container elements to apply container CSS classes from the theming framework:. tabs HTML div uI div CSS ui-widget ui-widget-header ui-widget-content Here we can see how Software Universal Product Code version A the HTML elements of the tabs widget relate to the CSS classes of the theming framework. The first HTML div element is the outer container of the tabs widget and has the ui-widget CSS class applied to it. The ul HTML element defines the header of the tabs widget.

The header contains the individual tabs. The tab"s ul header element has a ui-widget-header CSS class applied to it. Finally, the last div HTML element contains the selected tab content and has a ui-widget-content CSS class applied to it.

These three CSS classes are the containers of the jQuery UI theming framework. We"ll spend the rest of this chapter divulging the details of these theme classes..

The ui-widget class As we"ve seen in th GTIN - 12 for None e previous section, the ui-widget class is applied to all jQuery UI widgets at the outer-most layer. The styles defined by this class are applied to widget elements in a cascading fashion (like any CSS class applied to an outer HTML element) until they"re overridden by other styles. The ui-widget class defines font settings for all our jQuery UI widgets.

We"ve actually seen this in action in the previous chapter. The ThemeRoller application used to build custom jQuery UI themes - allows us to define font style properties. These changes affect every widget.

This consistent property of jQuery UI themes is made possible by the ui-widget class.. [ 76 ]. 4 . Now that we underst and, a little better, the role of the ui-widget class, it"s time to take a deeper look at the underlying CSS.. Time for action - preparing the example Here, we"re going t o set up an example that we can reuse throughout the chapter:. 1. 2..

If you haven"t alre ady, download and extract the jQuery UI package into a directory called jqueryui from http://jqueryui.com/download. At the same level as the jqueryui directory, create a new index.

html file with the following content:. <html xmlns="htt UPC-A Supplement 5 for None p://www.w3.org/1999/xhtml"> <head> <title>Working With Widget Containers</title> <link href="jqueryui/developmentbundle/themes/base/jquery.

ui.all.css" rel="stylesheet" type="text/css" /> </head> <body style="font-size: 10px;"> <div class="ui-widget">My Widget Container</div> </body> </html>.

Open index.html in a web browser. You should see something similar to the following:.

What just happened We"ve created a sim ple HTML file that we"ll use throughout the rest of the chapter. The first thing you"ll notice that is different about this HTML file is the path we"re using to include the theme CSS. We"re pointing to the development-bundle instead of CSS in the path.

Additionally, instead of importing a CSS file with a name such as jquery-ui-versioncustom.css, we"re importing jquery.ui.

all.css..
