<p>Ans:<br>
No, because dynamically loading of CSS file is not supported in flex. you can
compile the CSS file in swf and use it dynamically in your application. Loading
style sheets at run time is a three-step process:<br>
1. Write a CSS file for your application.<br>
2. Compile the CSS file into a SWF file.<br>
3. Call the StyleManager.loadStyleDeclarations() method in your Flex
application. This method loads the CSS-based SWF file into your application.
When this method executes, Flex loads the new CSSStyleDeclarations into the
StyleManager.<br>
<br>
For Example:<br>
&lt;?xml version=&quot;1.0&quot;?&gt;<br>
&lt;mx:Application xmlns:mx=&quot;http://www.adobe.com/2006/mxml&quot;&gt;<br>;
&lt;mx:Script&gt;<br>
&lt;![CDATA[<br>
import mx.styles.StyleManager;<br>
public function applyRuntimeStyleSheet():void {<br>
StyleManager.loadStyleDeclarations(&quot;../assets/BasicStyles.swf&quot;)<br>
}<br>
]]&gt;<br>
&lt;/mx:Script&gt; <br>
&lt;mx:Label text=&quot;Click the button to load a new CSS-based SWF file&quot;/&gt;<br>
&lt;mx:Button id=&quot;b1&quot; label=&quot;Click Me&quot; click=&quot;applyRuntimeStyleSheet()&quot;/&gt;<br>
&lt;/mx:Application&gt;<br>
