css - 如何使用 CSS 在悬停时添加不同的 CSS3 悬停过渡

Question

我的问题具体涉及使用 CSS 尝试在悬停时使用不同的 CSS 背景过渡，而不是悬停时的过渡。

这个问题引用了 Ian Lunn GitHub CSS3 Hover effects 提供的 CSS3 悬停效果。

See codepen here ，或查看下面的代码。代码:

<style>

.hvr-shutter-in-horizontal {
  display: inline-block;
  vertical-align: middle;
    background: rgba(121,61,61, 0.7);

    -webkit-transform: translateZ(0);
    transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  -webkit-transition-property: color;
  transition-property: color;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
}
.hvr-shutter-in-horizontal:before {
  content: "";
  position: absolute;
  z-index: -1;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
    background: rgba(77,79,79, 0.7);

  -webkit-transform: scaleX(1);
  transform: scaleX(1);
  -webkit-transform-origin: 50%;
  transform-origin: 50%;
  -webkit-transition-property: transform;
  transition-property: transform;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-timing-function: ease-out;
  transition-timing-function: ease-out;
}
.hvr-shutter-in-horizontal:hover, .hvr-shutter-in-horizontal:focus, .hvr-shutter-in-horizontal:active {
  color: white;
}
.hvr-shutter-in-horizontal:hover:before, .hvr-shutter-in-horizontal:focus:before, .hvr-shutter-in-horizontal:active:before {
  -webkit-transform: scaleX(0);
  transform: scaleX(0);
}
</style>

我想更改此按钮的鼠标移开，使其与以下 CSS 生成的鼠标移开相同:

/* Sweep To Bottom */
.hvr-sweep-to-bottom {
  display: inline-block;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  -webkit-transition-property: color;
  transition-property: color;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
}
.hvr-sweep-to-bottom:before {
  content: "";
  position: absolute;
  z-index: -1;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: #2098d1;
  -webkit-transform: scaleY(0);
  transform: scaleY(0);
  -webkit-transform-origin: 50% 0;
  transform-origin: 50% 0;
  -webkit-transition-property: transform;
  transition-property: transform;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-timing-function: ease-out;
  transition-timing-function: ease-out;
}
.hvr-sweep-to-bottom:hover, .hvr-sweep-to-bottom:focus, .hvr-sweep-to-bottom:active {
  color: white;
}
.hvr-sweep-to-bottom:hover:before, .hvr-sweep-to-bottom:focus:before, .hvr-sweep-to-bottom:active:before {
  -webkit-transform: scaleY(1);
  transform: scaleY(1);
}

Answer 1

这是一个概念示例，它为鼠标悬停时的高度和鼠标移开时的颜色设置动画

基于评论，它使用伪元素更新

div {
  position: relative;
  height: 30px;
  background: red;
  transition: background 1s;
}
div:after {
  content: '';
  position: absolute;
  left: 50%;
  top: 0;
  right: 0;
  height: 100%;
  background: red;
  transition: background 1s;
}

div:hover {
  height: 120px;
  background: blue;
  transition: height 1s;
}
div:hover:after {
  top: 100%;
  background: yellow;
  transition: top 1s;
}

<div></div>
