CSS 动画线在悬停时增长

CSS Animation Line Grow on Hover

我有一个悬停时需要动画的按钮。下图显示了单词 "Read More" 我希望右侧的黄线在悬停时比当前大小扩大约 %50。

<a href="#" class="read_more">Read More </a> .read_more { font-family: "Gotham SSm A", "Gotham SSm B"; font-size: 20px; color: #002c77; letter-spacing: 0; text-align: center; line-height: 28px; font-weight: bold; text-transform: uppercase; } .read_more::after { content: "14"; color: #fcd450; }

伪代码,因为看起来你什么都没有,但是

.line {
  width: 100px;
  transition: width .5s ease-in-out;
}
.line:hover {
  width: 150px;
}

见下文。希望这有帮助

.read_more {
  font-family: "Gotham SSm A", "Gotham SSm B";
  font-size: 20px;
  color: #002c77;
  letter-spacing: 0;
  text-align: center;
  line-height: 28px;
  font-weight: bold;
  text-transform: uppercase;
}

div {
  position: relative;
  display: inline-block;
}

div:after {
  content: "";
  height: 3px;
  width: 20px;
  background-color: red;
  position: absolute;
  right: -20px;
  top: 50%;
  transform: translateY(-50%);
}

div:hover:after {
  width: 30px;
  right: -30px;
}
<div><a href="#" class="read_more">Read More</a></div>

根据你自己的代码,我认为这实现了你所追求的! :)

将其粘贴到您自己的项目中后,字体和诸如此类的东西就会起作用。

.read_more {
  font-family: "Gotham SSm A", "Gotham SSm B";
  font-size: 20px;
  color: #002c77;
  letter-spacing: 0;
  text-align: center;
  line-height: 28px;
  font-weight: bold;
  text-transform: uppercase;
}

.read_more:after {
  content: '';
  position: relative;
  display: inline-block;
  width: 20px;
  height: 2px;
  vertical-align: top;
  margin-top: 12px;
  background-color: #fcd450;
  transition: width 0.3s ease;
}
.read_more:hover:after {
  width: 30px;
}
<a href="#" class="read_more">Read More </a>
