I'm not sure why this basic CSS isn't functioning...
.app a {
height: 18px;
width: 140px;
padding: 0;
overflow: hidden;
position: relative;
margin: 0 5px 0 5px;
text-align: center;
text-decoration: none;
text-overflow: ellipsis;
white-space: nowrap;
color: #000;
}
<div class="app">
<a href="">Test Test Test Test Test Test</a>
</div>
