<hr><a name="_details"></a><h2>Detailed Description</h2>
A CSS rule based on a template widget.
<p>
This is a CSS rule whose CSS style properties are defined based on properties of a template widget. When modifying the template widget, these changes are reflected on the CSS rule and thus all widgets that have this CSS rule.<p>
Usage example: <div class="fragment"><pre class="fragment"> <a class="code" href="classWt_1_1WCssTemplateRule.html" title="A CSS rule based on a template widget.">Wt::WCssTemplateRule</a> *styleRule = <span class="keyword">new</span> <a class="code" href="classWt_1_1WCssTemplateRule.html" title="A CSS rule based on a template widget.">Wt::WCssTemplateRule</a>(<span class="stringliteral">"#"</span> + <span class="keywordtype">id</span>() + <span class="stringliteral">" .item"</span>);
