You can do something like this:

$('.tile').prepend('<div class="tr"></div>')
               .prepend('<div class="tl"></div>')

.tile {
    position: relative;
    margin: 10px;
    width: 200px;
    height: 15px;
    padding: 20px;
    background-color: #ccc;
    text-align: center;
}

.tile .tl, .tile .tr,
.tile .bl, .tile .br {
    width: 0; 
    height: 0;
    position: absolute;        
}

.tile .tl {
    top: 0;
    left: 0;
    border-top: 60px solid white; 
    border-right: 20px solid transparent;
}
.tile .tr {
    top: 0;
    right: 0;
    border-top: 60px solid white; 
    border-left: 20px solid transparent;
}
