Question

我试图制作一个纯HTML和CSS的导航栏，它不需要任何JavaScript打开和关闭。

我的导航栏仍然存在问题。当我设置display: none或visibility: hidden以获得所需功能时，超链接不再起作用。

这可能吗？谢谢！

Answer 1

当你使用display：flex时，position：absolute，relative和fixed的行为不符合预期。检查这个link

修改了标记和css。请检查以下代码段

* {
  font-family: sans-serif;
}
nav {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-around;
  background-color: white;
  align-items: center;
  box-sizing: border-box;
  box-shadow: 0 0 2px rgba(128, 128, 128, 0.5);
}
nav div {
  height: 5vh;
  width: 10vw;
  position: fixed;
  top: 0;
  padding: 3px;
  right: 0;
}
.icon {
  display: inline;
}
nav > h1 {
  font-family: cursive;
  font-size: 1.2rem;
  padding-left: 10px;
  color: blue;
}
nav li {
  list-style: none;
  display: inline;
  font-size: 1.2rem;
  padding: 10px;
  cursor: pointer;
}
nav a {
  color: darkgray;
  text-decoration: none;
}
nav a:hover {
  color: black;
}
nav a:active {
  color: blue;
}
nav li:first-child * {
  color: blue;
}
nav ul {
  width: 50vw;
}
nav h1,
nav ul {
  font-size: 2rem;
}
nav > input {
  display: none;
}
nav > label {
  display: none;
}
input {
  display: none;
}
section {
  font-size: 2rem;
  padding: 1vh 5vh 0 5vh;
}
section#top {
  margin-top: 5.5vh;
}
@media (max-width: 5000px) {
  /* changed to 5000 so it is always collapsed */
  nav {
    height: 6vh;
    text-align: center;
    justify-content: space-between;
  }
  nav li {
    display: block;
    border: solid 1px blue;
    margin: 0 auto;
  }
  #links {
    visibility: hidden;
  }
  section#top {
    margin-top: 10vh;
  }
  input:checked + nav ul#links {
    visibility: visible;
    position: absolute;
    right: 30px;
  }
  input:not:checked +nav ul#links {
    visibility: hidden;
  }
  nav {
