.container {
border: 1px solid #DDDDDD;
width: 200px;
height: 200px;
position: relative;
}
.tag {
float: left;
position: absolute;
left: 0px;
top: 0px;
z-index: 1000;
background-color: #92AD40;
padding: 5px;
color: #FFFFFF;
font-weight: bold;
}
<div class="container">
<div class="tag">Featured</div>
<img src="http://www.placehold.it/200x200">
</div>
