Question

我希望悬停时出现的下划线效果具有app的填充/边距。 5px来自文本，只是在它们之间有一些空间。

以下是Codepen的代码和链接：

谢谢！

* {
  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: 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>

变体＃01：

在以下选择器中增加或减少bottom值：

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

＆＃13;

* {
  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);
}

＆＃13;

<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>

＆＃13;

变体＃02：

在<a>上设置以下css：

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

＆＃13;

* {
  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);
}

＆＃13;

<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

这是一个解决它的codepen：http://codepen.io/anon/pen/zowLZp

在padding-bottom: 4px规则中添加li > a，从li＆gt;中移除height: 1px。 a：在rule, and add a border-bottom：1px solid white to the same rule。

Answer 4

将此添加到您的css： li＆gt; ：悬停

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

检查以下代码段。

＆＃13;
＆＃13;
* { 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); }
＆＃13;
<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>
＆＃13;
＆＃13;
＆＃13;

Answer 5

只需将bottom选择器中li > a:before的值更改为-5px即可。如果您不想使用负值，可以使用top: 20px之类的内容并移除bottom: -5px。

＆＃13;

* {
  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);
}

＆＃13;

<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>
