Question

伙计们我解释我的问题...... 我正在开发移动菜单（代码非常长），我想使用“粘性标题”

这不是问题，因为使用js，当我滚动页面时代码添加了这个类来修复标题

.fixed {
 position: fixed;
 top: 0;
 z-index: 999;
}

我的标题有height: 90px，当我点击图标时出现菜单，我想它会出现在标题下面（并且菜单必须是一个div，覆盖整个页面除了标题），所以我我想我必须在菜单上添加position: fixed和top: 90px吗？问题是它不可分解后......

我试图添加

overflow-y: scroll;
overflow-x: hidden;

但不起作用...... 真诚地，如果有另一种方式而不是使用overflow它会更好（因为我讨厌由溢出创建的第二个滚动条）......

我希望你能帮助我，如果我没有例子，我很抱歉......

感谢

将菜单包装在固定的div中
将max-height: 100%和overflow: scroll添加到菜单中以启用滚动功能（就像它是iframe一样）

JSFiddle Example

#fixedWrapper {
  background:yellow;
  position:fixed;
  height: 50%;
  width:100%;
  /*centering*/
  left:0;
  right:0;
  margin:0 auto;
}

ul {
  margin:0;
  padding: 0;
  list-style:none;
  max-height:100%;
  overflow: scroll;
}

li a {
  display:block;
  padding:2em;
  background:black;
  color:#FFF;
  text-decoration: none;
  margin:2em;
  transition:.3s;
}

li a:hover {
  background:#FFF;
  color:#000;
}

p {
  background:#EEE;
  padding:2em;
}

<div id="fixedWrapper">
  <ul>
    <li><a href="#">Link 1</a></li>
    <li><a href="#">Link 2</a></li>
    <li><a href="#">Link 3</a></li>
    <li><a href="#">Link 4</a></li>
    <li><a href="#">Link 5</a></li>
    <li><a href="#">Link 6</a></li>
    <li><a href="#">Link 7</a></li>
    <li><a href="#">Link 8</a></li>
    <li><a href="#">Link 9</a></li>
    <li><a href="#">Link 10</a></li>
  </ul>
</div>

有一个div固定并滚动它？
