简单的css缩放动画,仿腾讯新闻的分享按钮和美团app底部的图标样式

最近看到一些好看的hover的图形缩放效果。然后自己就写了下,发现这2种效果都不错。如果伙伴们更好的实现方式可以在下面留言哦~

还有美团的效果,我就不展示了,喜欢的可以去app应用上看看。

这两种效果,其实实现的原理是一样的,就是用伪类选择器改变背景大小/图片大小。加一个过渡

    <!--腾讯新闻效果-->
    <a href="javascript:void(0);"  class="hover-body  hover-body-weixin">
        <i></i>
        <span></span>
    </a>
    <!--美图APP效果-->
    <a href="javascript:void(0);"  class="hover-body-app  third-party-app">
        <i></i>
    </a>

腾讯新闻小logo:外部的a标签实现点击跳转,我这里设置不跳转,i标签使用伪元素代表前景色和背景色,伪元素定位在里面,然后用缩放属性,在伪元素后面放过渡效果

.hover-body {
  position: relative;
  display: inline-block;
  width: 48px;
  height: 48px;
}

.hover-body:hover i::after {
  transform: scale(1);
}

.hover-body span {
  position: relative;
  display: block;
  width: 48px;
  height: 48px;
  background-size: 30px;
  background-position: center;
  background-repeat: no-repeat;
}

.hover-body i {
  position: absolute;
  top: 0;
  left: 0;
  width: 48px;
  height: 48px;
}

.hover-body i::before {
  content: '';
  border-radius: 50%;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

.hover-body i::after {
  content: '';
  transition: all .3s;
  border-radius: 50%;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  transform: scale(0);
}

.hover-body.hover-body-weixin span {
  background-image: url(index.png);
}

.hover-body.hover-body-weixin i::before {
  background-color: pink;
}

.hover-body.hover-body-weixin i::after {
  background-color: palegoldenrod;
}

美团app仿效果:css,直接在i标签里放背景图片,设置伪元素before和after为2张图片,给图片放大小,加过渡

.hover-body-app{
    position: relative;
    display: inline-block;
    width: 48px;
    height: 48px;
    margin-left: 6%;
    margin-right: 6%;
}
.hover-body-app:hover  i::after{
    transform: scale(1);
}

.hover-body-app i{
    position: absolute;
    top: 0;
    left: 0;
    width: 48px;
    height: 48px;
}
.hover-body-app i::before{
    content: '';
    border-radius: 50%;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
}
.hover-body-app i::after {
    content: '';
    transition: all .3s;
    border-radius: 50%;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    transform: scale(0);
}

.hover-body-app.third-party-app i::before {
    background: url(index.png);
    background-size: 30px;
    background-position: center;
    background-repeat: no-repeat;
}

.hover-body-app.third-party-app i::after {
    background: url(indexfull.png);
    background-size: 30px;
    background-position: center;
    background-repeat: no-repeat;
}
