I’m not sure how to get it on your home page, but my guess is to find the code for the hover and figure out how it’s placed over the images it shows up on. Then copy that code onto your style.css.
I have a Firefox extension called Firebug. It lets your right click anything in the webpage and it’ll take you straight to the code in the HTML or CSS. After that you can search for the code in your autofocus folder to see what php it’s coming from. It also lets you temporarily edit code on the fly to see what it’ll do to the webpage, then you just click refresh when you want a new start.
If i didn’t have this i woudn’t be able to get anything done…
