CSS-具有可见性的元素：隐藏不滚动

Question

I have a wrapper and an inner-wrapper as a child element of the wrapper. The inner-wrapper should scroll inside the wrapper and should have visibility hidden.

This works fine in computer browsers. However, the inner wrapper doesn't scroll when I open the page in a mobile browser.

What is the problem?

HTML:

<div id="wrapper">
  <div id = "inner-wrapper">
    <div id = "circle"></div>
    <div id = rectangle></div>
  </div>
</div>
<button>
  button
</button>

CSS:

#wrapper{
  position: fixed;
  top: 0px;
  width: 1px;
  height: 200px;
  z-index: 99999999;
}

#inner-wrapper{
  width: 300px;
  height: 200px;
  overflow: auto;
  z-index: 99999999;
}
#circle{
  height: 300px;
  width: 300px;
  border-radius: 100%;
  background-color: black;
  z-index: 99999999;

}
#rectangle{
  margin-top: 100px;
  height: 200px;
  width: 300px;
  background-color: red;
  z-index: 99999999;

}
button{
  z-index: 1;
  background-color: white;
}

You may consider using the following property:

-webkit-overflow-scrolling: touch;

Also be sure to set:

overflow:scroll;
