DHTML intrinsic behavior gives advantage to changing the user's home page to the current page.
The style block, which goes in the <HEAD> of the document, associates the home page class with the built-in behavior. The inline STYLE on the <SPAN> tag simulates the look and feel of a hot link, but clicking the link doesn't cause a new page to be loaded (IE5 also provides a new feature, to use conditional comments to hide this link from lower browsers).
The style block goes in the page <HEAD>:
This code can be placed anywhere in the page body:
<!--#if IE 5#>
Make this your home page</SPAN></U>
We can also change the user's home page to a page other than the current page by replacing window.location in the above example with a specific URL.
Internet Explorer first asks the user if they want to change their home page rather than setting it automatically.
