i see can use php.

you can check current uri on url , if matches add class 'active' on desired li add underline style :)

this job:

html

<div id="navbar" class="collapse navbar-collapse">  <ul class="nav navbar-nav" id="nav">     <li class="<?php echo (strpos($_server['request_uri'], "index") !== false) ? 'active' : '' ?>"><a href="index.php">home</a></li>     <li class="<?php echo (strpos($_server['request_uri'], "jobslist") !== false) ? 'active' : '' ?>"><a href="jobslist.php?id=3">bank job</a></li>     <li class="<?php echo (strpos($_server['request_uri'], "boardresult") !== false) ? 'active' : '' ?>"><a href="boardresult.php">board result</a></li>     <li class="<?php echo (strpos($_server['request_uri'], "admitcard") !== false) ? 'active' : '' ?>"><a href="admitcard.php">admit card</a></li>     <li class="<?php echo (strpos($_server['request_uri'], "anskey") !== false) ? 'active' : '' ?>"><a href="anskey.php">answer key </a></li>     <li class="<?php echo (strpos($_server['request_uri'], "timetable") !== false) ? 'active' : '' ?>"><a href="timetable.php">time table </a></li>  </ul> </div> 

or can try

<li class="<?= (strpos($_server['request_uri'], "index") !== false) ? 'active' : '' ?>"><a href="index.php">home</a></li> 

css

#nav li.active {   /* apply styles want on active anchors*/   border-bottom: 1px solid red; }
