CSS 问题，选中状态不会改变样式

Question

所以为了简单起见，我想只使用 html 和 css 来制作一个响应式导航栏，但是我遇到了一个问题，我试图使用一个复选框来制作一个汉堡菜单，所以当我单击它时，它会在其下方显示导航栏，但是当我单击选中状态时，显然不起作用

/*Navbar*/
nav{
    height: 75px;
    width: 100%;

    display: none;
}

#check:checked ~ .nav-list{
    height: 100vh;
}
#check:checked ~ .nav-list li{
    display: block;
}

如果你能帮助我，我将不胜感激，我只是一个对这些东西几乎一无所知的学生

Answer 1

尝试添加 !important

#check:checked ~ .nav-list{
    height: 100vh !important;
}

#check:checked ~ .nav-list li{
    display: block !important;
}

Answer 2

您的 CSS 正在尝试以 #check 为目标（这是一个 ID selector），但复选框没有 id "check"。

此外，general sibling combinator 仅适用于兄弟姐妹。所以 #check:checked~.nav-list 在 <input> 和 <label> 周围有 <div> 时不起作用，因为 #check 和 .nav-list 不是兄弟姐妹。

nav {
  width: 100%;
  background-color: #202020;
  display: flex;
  justify-content: space-between;
}

.nav-list {
  list-style: none;
  position: fixed;
  width: 100%;
  height: 0vh;
  top: 75px;
  background-color: #2f2f2f;
  transition: all .5s;
}

.nav-list li {
  display: none;
}

.hamburger-btn {
  font-size: 30px;
  color: white;
  line-height: 75px;
}

#check {
  display: none;
}

#check:checked~.nav-list {
  height: 100vh;
}

#check:checked~.nav-list li {
  display: block;
}
