<nav class="navbar navbar-default" role="navigation"> 
<div class="container"> 
    <div class="navbar-header"> 
     <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
     </button> 
     <a class="navbar-brand" href="<?php echo base_url(); ?>">love</a> 
    </div> 

    <!-- Collect the nav links, forms, and other content for toggling --> 
    <div class="collapse navbar-collapse" id="myNavbar"> 
     <ul class="nav navbar-nav"> 
      <li><a href="<?php echo base_url(); ?>">Home</a> 
      </li> 
      <li><a href="<?php echo base_url(); ?>about">About</a> 
      </li> 
      <li><a href="<?php echo base_url(); ?>contact">Contact</a> 
      </li> 
      <li><a href="<?php echo base_url(); ?>blog">Help</a>
