变体＃01：

在以下选择器中增加或降低bottom值：

li > a:before {
    bottom: -5px;  /* Change in this value will increase or decrease gap */
}

* {
  background-color: blue;
}
nav ul li {
  display: inline-block;
  padding-left: 35px;
  font-size: 12px;
  font-weight: bold;
}
/*Underline animation*/
li > a {
  position: relative;
  color: white;
  text-decoration: none;
}
li > a:hover {
  color: yellow;
}
li > a:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 1px;
  bottom: -5px;
  background-color: yellow;
  visibility: hidden;
  transform: scaleX(0);
  transition: all 0.1s ease-in-out 0s;
}
li > a:hover:before {
  visibility: visible;
  transform: scaleX(1);
}

<nav class="menu" id="menu">
  <ul>
    <li><a href="#">ABOUT</a></li>
    <li><a href="#">SERVICE</a></li>
    <li><a href="#">WORK</a></li>
    <li><a href="#">BLOG</a></li>
    <li><a href="#">CONTACT</a></li>
  </ul>
</nav>

变体＃02：

在<a>上的CSS之后设置：

li > a {
    display: inline-block;
    vertical-align: top;
    padding-bottom: 5px; /* Change in padding-bottom value will increase or decrease gap */
}

* {
  background-color: blue;
}
nav ul li {
  display: inline-block;
  padding-left: 35px;
  font-size: 12px;
  font-weight: bold;
}
/*Underline animation*/
li > a {
  display: inline-block;
  vertical-align: top;
  padding-bottom: 5px;
  position: relative;
  color: white;
  text-decoration: none;
}
li > a:hover {
  color: yellow;
}
li > a:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 1px;
  bottom: 0;
  background-color: yellow;
  visibility: hidden;
  transform: scaleX(0);
  transition: all 0.1s ease-in-out 0s;
}
li > a:hover:before {
  visibility: visible;
  transform: scaleX(1);
}

<nav class="menu" id="menu">
  <ul>
    <li><a href="#">ABOUT</a></li>
    <li><a href="#">SERVICE</a></li>
    <li><a href="#">WORK</a></li>
    <li><a href="#">BLOG</a></li>
    <li><a href="#">CONTACT</a></li>
  </ul>
</nav>

li > a:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 1px;
  bottom: -5px;
  background-color: yellow;
  visibility: hidden;
  transform: scaleX(0);
  transition: all 0.1s ease-in-out 0s;

}

将bottom: -5px;添加到li > a:before

Answer 3

这是一个解决该问题的代码epen：http：//codepen.io/anon/pen/zowlzp

将padding-bottom: 4px添加到li > a规则中，从li> a中删除height: 1px：在rule, and add a Border-Bottom之前：1px固体白色"到同一规则"。

Answer 4

将其添加到您的CSS： li> a：hover

li > a:hover {
  color: yellow;
  padding-bottom:5px;
}

检查下面的代码段。

* {
  background-color: blue;
}
nav ul li {
  display: inline-block;
  padding-left: 35px;
  font-size: 12px;
  font-weight: bold;
}
/*Underline animation*/
li > a {
  position: relative;
  color: white;
  text-decoration: none;
}
li > a:hover {
  color: yellow;
  padding-bottom:5px;
}
li > a:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 1px;
  bottom: 0;
  background-color: yellow;
  visibility: hidden;
  transform: scaleX(0);
  transition: all 0.1s ease-in-out 0s;
}
li > a:hover:before {
  visibility: visible;
  transform: scaleX(1);
}

<nav class="menu" id="menu">
  <ul>
    <li><a href="#">ABOUT</a></li>
    <li><a href="#">SERVICE</a></li>
    <li><a href="#">WORK</a></li>
    <li><a href="#">BLOG</a></li>
    <li><a href="#">CONTACT</a></li>
  </ul>
</nav>

Answer 5

只需将li > a:before选择器中bottom的值更改为-5px即可。如果您不想使用负值，则可以使用top: 20px之类的东西并删除bottom: -5px。

* {
  background-color: blue;
}
    
nav ul li {
  display: inline-block;
  padding-left: 35px;
  font-size: 12px;
  font-weight: bold;
}
    
    
/*Underline animation*/
    
li > a {
  position: relative;
  color: white;
  text-decoration: none;
}
    
li > a:hover {
  color: yellow;
}
    
li > a:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 1px;
  bottom: -5px;
  background-color: yellow;
  visibility: hidden;
  transform: scaleX(0);
  transition: all 0.1s ease-in-out 0s;
}
    
li > a:hover:before {
  visibility: visible;
  transform: scaleX(1);
}
    
    

<nav class="menu" id="menu">
  <ul>
    <li><a href="#">ABOUT</a></li>
    <li><a href="#">SERVICE</a></li>
    <li><a href="#">WORK</a></li>
    <li><a href="#">BLOG</a></li>
    <li><a href="#">CONTACT</a></li>
  </ul>
</nav>
