<h1>Getting CSS Style Sheets</h1>
<div class="exampleIntro">
<p><a href="http://developer.yahoo.com/yui/get">The YUI Get Utility</a> can be
used to fetch CSS stylesheets after the page has loaded. This allows you to
reduce the size of your "main" stylesheet by segregating the style rules for
specific modules that may not be displayed when the page is first rendered.
Once the module is needed, you can bring in the CSS (and JavaScript)
dynamically using the Get Utility.</p>
<p>The example below demonstrates the dynamic addition and removal of three
stylesheets that change the appearance of the News module. By clicking on the
buttons (which make use of the <a
href="http://developer.yahoo.com/yui/button/">YUI Button Control</a>), you can
add/remove border, background, and font treatments for the module.
(<strong>Note:</strong> The News module itself is built using the Get Utility
to fetch JSON data from the <a
href="http://developer.yahoo.com/search/news/V1/newsSearch.html">Yahoo! News
Search web service</a>; it follows the same code pattern described in the <a
href="get-script-basic.html">"Getting a Script Node with JSON Data"</a>
example.) </p>

<h1>Getting a Script Node with JSON Data</h1>
<div class="exampleIntro">
<p>This example employs the <a href="http://developer.yahoo.com/yui/get/">YUI Get Utility</a> in a simple use case: retrieving JSON data from a cross-domain web service. While this is a relatively common usage, it's important to understand the security ramifications of this technique. Scripts loaded via the Get Utility (or any other &quot;script node&quot; solution) execute immediately once they are loaded. If you do not fully control (or fully trust) the script's source, this is not a safe technique and it can put the security of your users' data at risk. (For more information on the dangers of cross-site scripting [XSS] exploits, <a href="http://en.wikipedia.org/wiki/Cross-site_scripting">check out the Wikipedia entry on this subject</a>.)</p>
<p>Here, we will use a trusted Yahoo! Search web service called <a href="http://developer.yahoo.com/search/siteexplorer/V1/inlinkData.html">Site Explorer</a> to return a list of inbound links for a given URL. The principal difference between this example and similar examples using <a href="http://developer.yahoo.com/yui/connection/">YUI Connection Manager</a> is that this technique does not require a server-side proxy. The browser connects directly to the third-party web service without bouncing through a proxy page as is required when using the XMLHttpRequest object (on which Connection Manager relies).</p>
