您可以使用伪元素:after和:before:

.line {
    width:70%;
}
.line:after {
    content:'';
    position: absolute;
    border-style: solid;
    border-width: 7px 7px 0;
    border-color: #FFFFFF transparent;
    display: block;
    width: 0;
    z-index: 1;
    top: 8px;
    left: 45%;
}
.line:before {
    content:'';
    position: absolute;
    border-style: solid;
    border-width: 7px 7px 0;
    border-color: #7F7F7F transparent;
    display: block;
    width: 0;
    z-index: 1;
    top: 9px;
    left: 45%;
}

<hr class="line">

您可以根据border-width需要调整大小.
