html - 菜单上的底部边框在 hoover 上延伸得太远

Question

我在我的页面上创建了一个响应式纯 css 菜单，除了悬停外，它工作得很好。悬停时，我需要它在菜单文本下绘制一条洋红色线。这已经有效，但是该行延伸到单词末尾之外太远了。它应该只强调这个词。我以前有过这个工作，所以我知道它可以完成，但那是通过不同的菜单实现的，我是通过随机敲击按键实现的，所以我不知道如何重复它。

这可能是重复的。我注意到另外两个相关的帖子，但我无法让他们的解决方案起作用，所以要么这是一个不同的问题，要么我不知道如何正确地将更改应用到我的代码。

这是目前的样子:

我稍微修改了你的 HTML 和 CSS，得到了 this :

HTML:已添加 <span>在 <a> :

<li>
  <a href="#about">
    <span>About</span>
  </a>
</li>

CSS:

.header li a {
  text-decoration: none;
  display: inline-block;
  height: 20px;
  padding: 8px 8px 8px 8px;
  font-family: HelveticaNeue-Thin;
  white-space: nowrap;
  color: #171581;
}

.header li a span {
  transition: 0.5s ease;
  border-bottom: 3px solid transparent;
}

.header li a:hover span {
  color: #D60053;
  border-bottom: 3px solid #D60053;
  border-bottom-width: 2px;
  padding-bottom: 2px;
  width: auto;
}

上一个(您的代码):

.header li a {
    text-decoration: none;
    display: inline-block;
    height: 20px;
    padding: 8px 8px 8px 8px;
    font-family: HelveticaNeue-Thin;
    border-bottom: 3px solid transparent;
    transition: 0.5s ease;
    white-space: nowrap;
    color: #171581;
}

.header li a:hover {
  color: #D60053;
  border-bottom: 3px solid #D60053;
  border-bottom-width: 2px;
  padding-bottom: 2px;
  width: auto;
}
