This section describes sidebar tabs and explains how tabs differ from ordinary web sites. Sidebar tabs are simple HTML pages and are easy to create. With robust support for web standards like HTML 4, JavaScript, XML, CSS, and DOM, you can also create powerful applications. All of this works without any server round trips to slow down the process. Tabs are like regular web pages in that they are built on HTML and other web standards.
Users can easily add and customize sidebar tabs.
Information that is well suited to a tab is that which is of continuous interest to the user. The content can be dynamic in the sense that the details may change often, but the information should always be relevant and up to date. For example, a stock ticker or news wire service present constantly changing particulars, but the user desires the presence of that information to be continuous. The default sidebar width is 144 pixels with a scroll bar and 162 pixels without a scroll bar. You can use any supported MIME type.
