css button按钮点击或者划过背景色填充
不会录制动图反正就是这个意思
下面是html
<a class="btn" href="#"><span></span></a>
css
.btn:active {background: #6a468e;}.btn{position: relative;display: block;margin: 20px auto;width: 100%;height: 80px;max-width: 250px;text-transform: uppercase;overflow: hidden;border: 1px solid currentColor;}a {text-decoration: none;line-height: 80px;color: black;}.btn:hover span {width: 562.5px;height: 562.5px;}.btn span {position: absolute;display: block;width: 0;height: 0;border-radius: 50%;background: #402a55;-webkit-transform: translate(-50%, -50%);transform: translate(-50%, -50%);-webkit-transition: width 0.6s, height 0.6s;transition: width 0.6s, height 0.6s;z-index: -1;}
