Hi Ravindranath M,
According to your description, I suggest you could add a click event for the a tag. Add css to one of the li and at the same time remove the other lis' css.
If this is not you need,you could post more details codes of css.
More details ,you could refer to below codes:
<script src="Scripts/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function () {
$('.nav-tabs li a').click(function () {
$(this).closest("li").addClass('highlight').siblings().removeClass('highlight');
return (false); // no default behavior from clicking on the link
})
})
</script>
<style>
.highlight {background-color: #F00; color: #FFF;}
.highlight a {color: #FFF;}
.nav-tabs li {display: inline; padding: 0 10px;}
.nav-tabs li a {text-decoration: none;}
</style>
<div>
<ul class="nav nav-tabs">
<li class="" id="request"><a href="#requesttab" data-toggle="tab">Requests</a></li>
<li id="Approval"><a href="#approvaltab" data-toggle="tab">Approval</a></li>
</ul>
</div>
Result:

Best regards,
