漣漪效應從按鈕的框內消失，我不希望這樣，但我不知道如何擺脫它。請幫忙？
body { background-color: #ddd; }
.overknop {
position: relative;
border-radius: 0 50px 0 50px;
border: 1px solid white;
font-family: "Bebas Neue";
font-size: 28px;
color: #FFFFFF;
color: black;
padding: 20px;
width: 200px;
overflow: hidden;
text-align: center;
text-decoration: none;
cursor: pointer;
background-color: transparent;
transition-duration: 0.4s;
}
.overknop::after {
content: "";
background: #f1f1f1;
display: block;
position: absolute;
padding-top: 300%;
padding-left: 350%;
margin-left: -20px !important;
margin-top: -120%;
opacity: 0;
transition: all 0.8s;
}
.overknop:active::after {
padding: 0;
margin: 0;
opacity: 1;
transition: 0s;
}<button class="overknop">OVER</button>真的不知道怎么做，在網上也找不到任何關于它的東西
uj5u.com熱心網友回復：
這作業正常。
您應該忘記overflow:hidden在代碼中使用
