html - 在悬停时在下划线和导航项之间添加一个空格

Question

我希望悬停时出现的下划线效果具有应用程序的填充/边距。距文本 5 像素，只是为了在文本之间留出一些空间。

这是 Codepen 的代码和链接:

变体#01:

增减bottom以下选择器中的值:

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 */
}

* {
  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>
