<div class="wrapper">
      <a href="http://www.facebook.com"><i class="fa fa-3x fa-facebook-square"></i></a>
      <a href="http://www.twitter.com"><i class="fa fa-3x fa-twitter-square"></i></a>
      <a href="http://www.instagram.com"><i class="fa fa-3x fa-instagram instagram"></i></a>
</div>

CSS

.wrapper {
  justify-content: center;
  align-items: center;
}
.wrapper i {
  padding: 10px;
  text-shadow: 0px 6px 8px rgba(0, 0, 0, 0.6);
  transition: all ease-in-out 150ms;
}
.wrapper a:nth-child(1) {
  color: #3b5998
}
.wrapper a:nth-child(2) {
  color: #1DA1F2;
}
.wrapper a:nth-child(3) {
  color: black;
}
.wrapper i:hover {
  margin-top: -3px;
  text-shadow: 0px 14px 10px rgba(0, 0, 0, 0.4);
}

我正在创建一个网站，其中社交媒体图标在悬停时响应，并且徽标有一个图标。
