This is the code:

 <!--Latest News-->
      <div class= "row ">
      <div class="col-md-8 ">
         <div class="well">
            <div class="well well-sm" style="background-color:#00805e;  margin-top:.5em; padding: 5px 0 0 20px; width:100%;  border-radius:5px">
               <h4 style="text-align:center; margin:.5em ; background-color:#333; padding: 10px 18px; width:11em;  border-radius:5px">
