.title {
    position: relative;
    color: $gray-color-1;
    text-align: center;
    margin-bottom: 10px;

    font-family: $decoration-text;
    font-size: 28px;

    &:before {
        content: '';
        position: absolute;
        top: 50%;
        /*background: $gray-color-8;*/
        border-bottom: 1px solid $gray-color-8;
        width: 35%;
        height: 1px;
        left: -1%;
    }

    &:after {
        content: '';
        position: absolute;
        top: 50%;
        /*background: $gray-color-8;*/
        border-bottom: 1px solid $gray-color-8;
        width: 35%;
        height: 1px;
        right: 1%;
    }
}

主要是利用:before与:after伪元素，为横向预留位置

利用position将伪元素与主元素定位，利用布局将其居中显示，然后划线，background与border均可。
