Using this thread I carried out my header into the individual html file
header.html:
<div class="navbar navbar-default navbar-fixed-top" id="top" role="banner">
<div class="container">
<div class="navbar-header">
<button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="navbar-collapse collapse" role="navigation" style="height: auto;">
<ul class="nav navbar-nav">
<li><a href="/page1.html">Page1</a></li>
<li><a href="/page2.html">Page2</a></li>
</ul>
</div>
</div>
</div>
and included it in my index.html.
<script src="https://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
$(function(){
$("#navbar-header").load("header.html");
$("#footer").load("footer.html");
});
</script>
and
<div id="navbar-header"></div>
My question is, how to apply 'active' class on selected page (page1 and page2)?
<li class="active"><a href="/page1.html">Equator Server</a></li>
