I\'m using bootstrap, trying to make a div have a CSS triangle before it.

Here is my non-working code:

.d:bef

    You need content property and some other

    .d:before {
      content: '';
      width: 0px;
      height: 0px;
      border-style: solid;
      border-width: 10px 15px 10px 0;
      border-color: transparent #dd4397 transparent transparent;  
      display: inline-block;
      vertical-align: middle;
      margin-right: 5px;
    }
