• For example to change link's background color in order to show user where is he/she located.. in css there is this snap of code a:active {background:#fff;} but it doesnt work because there is no loading of page – Zeid Selimovic Commented Jun 19, 2012 at 9:51

Since you're just starting out, I'd suggest you use a library such as jQuery. So, if your HTML is like this:

<div id="box1" class="box">
<h3><a name="box1">something</a></h3>
</div>
<div id="box2" class="box">
<h3><a name="box2">something</a></h3>
</div>
<div id="box3" class="box">
<h3><a name="box3">something</a></h3>
</div>

And you have a CSS class called youarehere:

.youarehere { color:white; background:green; }

With jQuery you could write something along the lines of:

$(".box > a").click(function() {             // when clicking any of these links
    $(".box > a").removeClass("youarehere"); // remove highlight from all links
    $(this).addClass("youarehere");          // add highlight to clicked link
})

In plain JS, it takes a bit more effort to achieve this. Do yourself a favor and don't reinvent the wheel - people have already taken care of this, so use the product of their labor to make your life easier.

a:active means when you click the link the css properties will apply on the link, instead of using a:active use

a.visited{color:red;}

To change the link text color on mouse over use the following css:

<style type="text/css">
        a:hover{color:Red;}
    </style>
