Question

点击按钮时，我试图设置涟漪效果。

我已经成功完成了，但它只能在谷歌浏览器的浏览器中使用，我不知道为什么。该效果未显示在Safari或FireFox中（尚未测试IE）。

HTML：

<p><b>NOTE:</b> This ripple effect is only working on Chrome browser.</p>
<button>Click Me</button>

CSS：

button {
    border: none;
    cursor: pointer;
    color: black;
    width: 130px;
    padding: 10px;
    border-radius: 2px;
    font-size: 19px;
    background: green;
    position: relative;
    overflow: hidden;
}

button:after {
    content: '';
    position: absolute;
    top: 50%;
    left: 50%;
    width: 5px;
    height: 5px;
    background: rgba(255, 255, 255, .5);
    opacity: 0;
    border-radius: 100%;
    transform: scale(1, 1) translate(-50%);
    transform-origin: 50% 50%;
}

@keyframes ripple {
    0% {
        transform: scale(0, 0);
        opacity: 1;
    }
    20% {
        transform: scale(25, 25);
        opacity: 1;
    }
    100% {
        opacity: 0;
        transform: scale(40, 40);
    }
}

button:focus:not(:active)::after {
    animation: ripple 1s ease-out;
}

button:focus{
    outline: none;
}

* { box-sizing:border-box; }

您需要为safari和chrome添加-webkit-，为mozila添加-moz-，为Opera浏览器添加-o-

button {
    border: none;
    cursor: pointer;
    color: black;
    width: 130px;
    padding: 10px;
    border-radius: 2px;
    font-size: 19px;
    background: green;
    position: relative;
    overflow: hidden;
}

button:after {
    content: '';
    position: absolute;
    top: 50%;
    left: 50%;
    width: 5px;
    height: 5px;
    background: rgba(255, 255, 255, .5);
    opacity: 0;
    border-radius: 100%;
    transform: scale(1, 1) translate(-50%);
    transform-origin: 50% 50%;
}

@keyframes ripple {
    0% {
        transform: scale(0, 0);
        opacity: 1;
    }
    20% {
        transform: scale(25, 25);
        opacity: 1;
    }
    100% {
        opacity: 0;
        transform: scale(40, 40);
    }
}
@-webkit-keyframes ripple {
    0% {
        transform: scale(0, 0);
        opacity: 1;
    }
    20% {
        transform: scale(25, 25);
        opacity: 1;
    }
    100% {
        opacity: 0;
        transform: scale(40, 40);
    }
}
@-moz-keyframes ripple {
    0% {
        transform: scale(0, 0);
        opacity: 1;
    }
    20% {
        transform: scale(25, 25);
        opacity: 1;
    }
    100% {
        opacity: 0;
        transform: scale(40, 40);
    }
}
@-o-keyframes ripple {
    0% {
        transform: scale(0, 0);
        opacity: 1;
    }
    20% {
        transform: scale(25, 25);
        opacity: 1;
    }
    100% {
        opacity: 0;
        transform: scale(40, 40);
    }
}

button:focus:not(:active)::after {
    animation: ripple 1s ease-out;
}

button:focus{
    outline: none;
}

* { box-sizing:border-box; }

在CSS代码中，有些属性没有工作标准，可能永远不会成为标准（transform，@ keyframes）。为了克服这个问题，我们使用Vendor Prefixes（-webkit，-moz）。
