CSS悬停在转换不起作用

Question

我正在为投资组合网站制作导航按钮，悬停工作完美，但一旦鼠标悬停，按钮会弹回原位，而不是慢慢过渡。

以下是代码：

li {
  list-style-type: none;
  margin: 20px 5px 0px 5px;
}
nav ul li a {
  display: block;
  margin: 30px 10px;
  text-decoration: none !important;
  text-align: center;
  width: 90px;
  padding: 6px 0;
  border-radius: 4px;
  -o-transition: all 300ms ease-in-out;
  -ms-transition: all 300ms ease-in-out;
  -webkit-transition: all 300ms ease-in-out;
  -moz-transition: all 300ms ease-in-out;
  transition: all 300ms ease-in-out;
  background: #E6E5CC;
  float: right;
  top: 0px;
  left: 0px;
}
nav ul li a:hover {
  color: inherit;
  position: relative;
  top: 0px;
  right: 0;
  bottom: 0;
  left: 0px;
  top: -5px;
  left: -5px;
  box-shadow: 1px 1px 0px #e3e2c5, 2px 2px 0px #dfdebe, 3px 3px 0px #cbc995, 4px 4px 0px #b4b165, 5px 5px 0px #56542a;
  background: #f7f6ee;
}
nav ul li a:active {
  color: inherit;
  top: 5px;
  left: 5px;
  box-shadow: 0px 0px 5px white;
}

<nav>
  <ul>
    <li>
      <a href="#">Contact</a>
    </li>
    <li>
      <a href="#">Projects</a>
    </li>
    <li>
      <a href="#">Blog</a>
    </li>
    <li>
      <a href="#">About</a>
    </li>
  </ul>
</nav>

只需将nav ul li a设置为position: relative;即可按预期运行。

您在position:relative规则中有:hover语句，但它应该处于原始状态规则中。此外，您有一些重复的重叠位置值。

li {
  list-style-type: none;
  margin: 20px 5px 0px 5px;
}
nav ul li a {
  display: block;
  margin: 30px 10px;
  text-decoration: none !important;
  text-align: center;
  width: 90px;
  padding: 6px 0;
  border-radius: 4px;
  -o-transition: all 300ms ease-in-out;
  -ms-transition: all 300ms ease-in-out;
  -webkit-transition: all 300ms ease-in-out;
  -moz-transition: all 300ms ease-in-out;
  transition: all 300ms ease-in-out;
  background: #E6E5CC;
  float: right;
  position: relative;
  top: 0px;
  left: 0px;
}
nav ul li a:hover {
  color: inherit;
  top: -5px;
  left: -5px;
  box-shadow: 1px 1px 0px #e3e2c5, 2px 2px 0px #dfdebe, 3px 3px 0px #cbc995, 4px 4px 0px #b4b165, 5px 5px 0px #56542a;
  background: #f7f6ee;
}
nav ul li a:active {
  color: inherit;
  top: 5px;
  left: 5px;
  box-shadow: 0px 0px 5px white;
}

<nav>
  <ul>
    <li>
      <a href="#">Contact</a>

将nav ul li a设置为position: relative;，如下所示：

nav ul li a {
  display: block;
  margin: 30px 10px;
  text-decoration: none !important;

  width: 90px;
  padding: 6px 0;
  border-radius: 4px;
  -o-transition: all 300ms ease-in-out;
