You need to make :before pseudo element absolute . Then use top to control the position of the pseudo element. This [this video] is a nice tutorial to understand the basics. Working code #bellnews { position: absolute; min-width: 140px; min-height: 100px; background: #fff; color: #000; border: 1px solid #000; width: 100px } #bellnews:before { content: ""; vertical-align: middle; margin-left: 70px; width: 0; height: 0; border-left: 5px solid transparent; border-right: 5px solid transparent; border-bottom: 5px solid black; position: absolute; top: -5px; } <div id=bellnews> </div>
