Empty line here in PhpStorm
What does PhpStorm have to do with an empty line:
Either
<br>
or
<div class="cf"></div>
where cf is:
.cf { content:".";
/*display:table;*/
width:100%;
display:block;
clear:both;
height: 10px;
font-size:0;
line-height:0;
visibility:hidden;
overflow:hidden; }
.cf:after { clear:both; } .cf { *zoom:1; }
* html .cf { zoom: 1; } /* IE6 */
*:first-child+html .cf { zoom: 1; } /* IE7 */
