<section id="about">
<div class="container">
<div class="row text-center">
<div class="col-md-6 col-sm-12 col-xs-12">
<img class="ratio" src="img/about1.jpg">
<div class="about-heading">Our Services</div>
<div>Replace this content with your own content. Content should be relevant, unique and written with the goal of providing the reader the type of information they are looking for while motivating them to take action.</div>
