Simple CSS highlight help

[BlaZe]

What deAthbLisS said is right.

Add this CSS code in your .css file

ul#navigation li.active1
{
    border-bottom: 1px solid #000;
    background: #304b0f;
}

Now whichever tab needs to be highlighted, add class="active1" for it.

Example:

<ul id="navigation">
                <li class="active"><a href="/">Home</a></li>
                <li class="active1"><a href="/myaccount">My Account</a></li>
                <li class="active"><a href="/editaccount">Edit Account</a></li>
                <li class="active"><a href="/logout">Logout</a></li>
</ul> 

Here, "My Account" will be highlighted.

If you need to edit the color, then change this background: #304b0f; (in the code I gave previously) as per your liking.
