Only in IE

overflow: hidden;
}

height:20px;
border-top: 60px double;
border-bottom: 20px solid;

boder color

same as box-shadow, text-shadow ...

<a class="add"/>
.add{
border: 1px solid #ccc;
}
.add:before, .add:after {
background: #ccc;
}
.add:hover{
border-color: #06c;
}
.add:hover:before, .add:hover:after {
background: #06c;
}
.add {
color: #ccc;
transition: color .25s;
border: 1px solid;
}
.add:before {
border-top: 10px solid;
}
.add:after {
border-left: 10px solid;
}
border position
background-position has limitation in CSS2.1, it can only position related to the left top
so we can use a transparent border as right padding
