                                <font><i class="fa fa-clock-o dvMarTop1 dvTimeItem"></i> &nbsp;20:00 | Chủ nhật, 15/06/2016</font>


But as you see I cannot set full background for col-sm-5 and set vertical center text

Either you didn't refresh your browser page after you edited the code or you didn't place your style.css under the other CSS links in the head part of the code.
