I'm trying to make my page do this effect for when you hover over the links, but I'm having a hard time figuring out how this person did it.

Here's the page (http://paginas.terra.com.br/informatica/layoutshouse/)

http://www.``````````````/transtutorial.shtml

Thanks, now I just have to fix up the details

Ok, where do I see the url I upload the file to?

Sorry, meant the one I uploaded the file to

I'm still confused about what I'm supposed to do

You take the code that you got from that site and insert it into your stylesheet. Then, whichever page you added your stylesheet into, that's where the link hover effect should appear :) .
