您可能会查看text-underline-offset，尽管（在撰写本文时）它仅与最新版本的主要浏览器兼容。

【解决方案1】：

使用边框代替下划线可以解决您的问题。试试这个代码。

ul.ml-auto > li > a > span{
    font: 15px Roboto,sans-serif;
    font-weight: 500;
    position: relative;
    display: inline-block;
    color: #FFFFFF80;
    overflow: hidden;
      padding-bottom: 5px;
    }
    ul.ml-auto > li > a > span::before {
    position: absolute;
    content: attr(data-content);
    color: #00FFFF;
    clip-path: polygon(0 0, 0 0, 0% 100%, 0 100%);
    transition: clip-path 275ms ease;
      display: block;
      border-bottom: 1px solid #00FFFF;
      padding-bottom: 3px;
    }

首先使用 text-decorate: underline 时不能修改间距

你的代码使用 <:before> 因为 span 是内联样式，然后它的间距会随着里面的内容而固定。

我的解决方案是为你和 <:before> 进行填充，然后在 :before 标签内使用border-bottom

ul.ml-auto > li > a > span{
   ///Adding bottom-padding here
   padding-bottom: 3px; // your spacing you want - 1 cause the border will take 1px of the height
}

ul.ml-auto > li > a > span::before {
   border-bottom: 1px solid red;
   padding-bottom:2px;
}

这里是一个示例 Html，用于在菜单中填充列表的顶部和底部

 <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> 
 <a class="navbar-brand" href="#">Navbar</a>
 <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
 <span class="navbar-toggler-icon"></span>
 </button>
 <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
 <ul class="ml-auto navbar-nav">
 <li class="nav-item">
 <a class="nav-link" href="">Contact</a>
 </li> 
 <li class="nav-item">
 <a class="nav-link" href="">About me</a>
 </li> 
 <li class="nav-item">
 <a class="nav-link" href="">Features</a>
 </li> 
  </ul> 
   </div>
  </nav>

here is the code for underline


li{
    text-decoration: underline;
    text-underline-position: under;
}
