Thank you for the clarification.
I wanted to add just another little feature to my 'products' list'. When the user clicks an anchor and while they are viewing those products, I want to change the text to bold and also add just a tad of letter spacing. If they click another, I want to take the style off the previous product and apply it to the current element.
How can I achieve this? I searched google and this forum but people posted more specific problems with IE or FF for example.
Do you know how to add this effect? I'm going to search around and see if I can find a site which implements this just so you can see exactly what I mean as I don't think my question is very clear.
Edit: Take a look at Google 
. When you click Web or Images for example, there is a red font applied to the links (used as a way to show what link you are on, this is what I wanted to do).
Kind regards,
LC.
