Question

有没有办法让我打开菜单时，它不会超出第一部分，或者菜单打开后会禁用滚动？我尝试给每个部分z-index 999，但这不起作用

HTML：

<section class="intro">
<label>
  <input type="checkbox">
  <span class="menu">
    <span class="hamburger"></span>
  </span>
  <ul>
    <li>
      <a href="#">Home</a>
    </li>
    <li>
      <a href="#">About</a>
    </li>
    <li>
      <a href="#">Contact</a>
    </li>
  </ul>
</label>
<div class="text">
<h1>my<br>example<br>text</h1>
</div>
</div>
</section>

<section class="first"> 

</section>

<section class="second">  

</section>


<section class="third">  

</section>

CSS：

/* Section styling */
body, html {
    height: 100%;
    margin: 0;
}

* {
  box-sizing: border-box;
}

section {
  width: 100%;
  display: table;
  margin: 0;
  max-width: none;
  height: 100vh;
}

.intro {
  background-color:#291411;

.first {
  background-color:#834940;
}

.second {
  background-color:#291411;
}

.third {
  background-color:#834940;
}
/* Hide scrollbars */
html {
    overflow: scroll;
    overflow-x: hidden;
}
::-webkit-scrollbar {
    width: 0px; 
    background: transparent; 
}
::-webkit-scrollbar-thumb {
    background: #FF0000;
}
/* Menu before */
label .hamburger {
  position: absolute;
  top: 135px;

label .hamburger:before { top: -10px; }

label .hamburger:after { bottom: -10px; }

label input { display: none; }

label input:checked + .menu {
  box-shadow: 0 0 0 100vw #E0C9B7, 0 0 0 100vh #E0C9B7;
  border-radius: 0;
}

label input:checked + .menu .hamburger {
  -webkit-transform: rotate(45deg);
  transform: rotate(45deg);
}

label input:checked + .menu .hamburger:after {
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
  bottom: 0;
}

label input:checked + .menu .hamburger:before {
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
  top: 0;
}

label input:checked + .menu + ul { opacity: 1; }
/* Menu after */
label .menu {
  position: absolute;
  right: -100px;
  top: -100px;
  z-index: 100;
  width: 200px;
  height: 200px;
  background: #E0C9B7;
  border-radius: 50% 50% 50% 50%;
  -webkit-transition: .5s ease-in-out;
  transition: .5s ease-in-out;
  box-shadow: 0 0 0 0 #E0C9B7, 0 0 0 0 #E0C9B7;
  cursor: pointer;
}

label ul {
  z-index: 200;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  opacity: 0;
  -webkit-transition: .25s 0s ease-in-out;
  transition: .25s 0s ease-in-out;
  list-style-type:none;
}

label a {
  margin-bottom: 1em;
  display: block;
  color: #291411;
  text-decoration: none;
}
/* Footer styling */
footer {
  padding: 1% 5%;
  text-align:center;
  background-color: #291411;
  color: #E0C9B7;
}

要在菜单打开时禁用滚动，我尝试将overflow-x：hidden添加到html和body中，但这会使整个页面变得奇怪

用jquery做了一个简单的解决方案，你可以用javascript做到这一点。我使用jquery只是为了节省时间。

$(".js-change").on("change", function() {
  $("html").toggleClass("menu-open");  
});
