使用CSS3动画按下按钮

Question

我试图在活动状态下按下一个斜角按钮。我希望过渡过程足够平稳，但问题是我不知道如何实现这种平稳。我所取得的成就如下:

.button {
  background-color: #ff962c;
  border-radius: 10px;
  width: 25%;
  text-align: center;
  color: #FFFFFF;
  padding: 10px;
  font-family: 'Source Sans Pro', sans-serif;
  display: inline-block;
  font-size: 20px;
  box-shadow: inset 2px 2px 2px rgba(255, 255, 255, .4), inset -2px -2px 2px rgba(0, 0, 0, .4);
}
.button:active {
  border: 1px solid #ff962c;
  background-color: #ffa346;
  box-shadow: inset 2px 2px 2px rgba(0, 0, 0, .8), inset -1px -1px 1px rgba(255, 255, 255, .4);
}
.button:hover {
  background-color: #ffa346;
}

<a href="" id="upload" class="button">
  <i class="fa fa-cloud-upload fa-lg fa-align-center" aria-hidden="true"></i>
</a>
<a href="" id="view" class="button">
  <i class="fa fa-eye fa-lg fa-align-center" aria-hidden="true"></i>
</a>

Answer 1

你可以添加css过渡。确切地说:transition: box-shadow .2s ease-in-out;。我建议只改变过渡的特定属性，特别是当我们谈论框阴影和其他沉重的效果。

.button {
  background-color: #ff962c;
  border-radius: 10px;
  width: 25%;
  text-align: center;
  color: #FFFFFF;
  padding: 10px;
  font-family: 'Source Sans Pro', sans-serif;
  display: inline-block;
  font-size: 20px;
  box-shadow: inset 2px 2px 2px rgba(255, 255, 255, .4), inset -2px -2px 2px rgba(0, 0, 0, .4);
  transition: box-shadow .2s ease-in-out;
}
.button:active {
  box-shadow: inset 2px 2px 2px rgba(0, 0, 0, .8), inset -1px -1px 1px rgba(255, 255, 255, .4);
}
.button:hover {
  background-color: #ffa346;
}

<a href="" id="upload" class="button">
  <i class="fa fa-cloud-upload fa-lg fa-align-center" aria-hidden="true"></i>
</a>
<a href="" id="view" class="button">
  <i class="fa fa-eye fa-lg fa-align-center" aria-hidden="true"></i>
</a>

您的意思是这样，仅仅使用transitions吗?
看看这个链接，它可能会很有用:hover.css

.button {
  background-color: #ff962c;
  border-radius: 10px;
  width: 25%;
  text-align: center;
  color: #FFFFFF;
  padding: 10px;
  font-family: 'Source Sans Pro', sans-serif;
  display: inline-block;
  font-size: 20px;
  box-shadow: inset 2px 2px 2px rgba(255, 255, 255, .4), inset -2px -2px 2px rgba(0, 0, 0, .4);
  -webkit-transition: all .1s ease;
  -moz-transition: all .1s ease;
  -o-transition: all .1s ease;
  transition: all .1s ease;
}
.button:active {
  border: 1px solid #ff962c;
  background-color: #ffa346;
  box-shadow: inset 2px 2px 2px rgba(0, 0, 0, .8), inset -1px -1px 1px rgba(255, 255, 255, .4);
}
.button:hover {
  background-color: #ffa346;
}

<a href="" id="view" class="button">
