How do I change the background colour of a dropdown?

Question

I can't get the background colour of my dropdown to change when it's open.

My CSS code is

.dropdown.open { background-color: black; }

My HTML is

<ul class="nav navbar-nav navbar-right"> <li><a href="#web-hidden" onClick="TypeWeb()">WEB DEVELOPMENT</a></li> <li><a href="#programming-hidden" onClick="TypeProgramming()">PROGRAMMING</a></li> <li><a href="#design-hidden" onClick="TypeDesign()">DESIGN</a></li> <li><a href="#game-hidden" ></a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false" onClick="TypeGameDesign()"> GAME DEVELOPMENT <span class="caret"></span> </a> <ul class="dropdown-menu"> <li><a href="#">Unity3D</a></li> <li role="separator" class="divider"></li> <li class="dropdown-header">Coming...</li> <li><a href="#">UE4</a></li> <li><a href="#">VR</a></li> </ul> </li> </ul>

Where is the function to open and close the li dropdown element? Shouldn't it have an onclick callback: <li class="dropdown" onclick="toggleState();"> — Javier Rey

The background color belongs to the a. So, use this:

.dropdown.open > a { background-color: #000 !important; }
