Flash Navigation Images?

I'm seeing several forums sites, where you can hover your cursor at the navigation image like "Home" on the top menu and something happens like, the whole image highlights, or something else pops up.

Does anyone have a basic code for that? Or teach me how to do that. (sorry, can't explain it though..hope you guys can understand what i'm talking about.)

Thank you in advance.

Hello,

You can't use flash in the forumotion nav bar.
You can make simple effects using CSS.
What version you use?

I use Phpbb2 version.
Can you tell me how to do the simple effects?

Well,

I can't teach you but if you tell me what effect you want, I'll tell you how to do it.

Awesome. I want to know how.

Go to Admin CP > Display > Colors >CSS
Add this codes there and submit. Then see the effect on the forum page.

Code:

a:link.mainmenu {
color : red;
}
a.mainmenu:hover {
color : green;
}

The above code will change color on hover..

This will make border around...

Code:

a:link.mainmenu {
padding : 3px;
}
a.mainmenu:hover {
border : 1px solid black;
}
