Bootstrap image header with title and coloured bar

It’s not rocket-science but, in case anyone else is looking how to do this, based on this post: http://forums.asp.net/t/2067649.aspx?bootstrap+thumbnail+image+with+text+inside+and+green+big+line+on+the+bottom

Html:

<div class="row">
 <div class="col-md-6">
  <div class="forum-image header-image">
   <div class="h3 heading-text">FORUM</div>
   <div class="heading-border"></div>
  </div>
  <div class="content-container"></div>
 </div>
 <div class="col-md-6">

   <div class="h3 heading-text">CALENDAR</div>
   <div class="heading-border"></div>
  </div>
  <div class="content-container"></div>
 </div>
</div>
