可调整大小的容器,其中包含的项目会溢出。将 overflow:visible 与可调整大小相结合

Resizable container with a contained item that overflow. Combine overflow:visible with resizability

我需要创建一个带有 上拉切换按钮 的容器 div(但这也可以是一个简单的跨度、标签或其他任何东西),但这也可以 re-sizable.

不幸的是(https://css-tricks.com/almanac/properties/r/resize/):

Super important to know: resize does nothing unless the overflow property is set to something other than visible, which is its initial value for most elements.


我试图写一个 simple example 来比较每个冲突属性的限制(下面只是一个摘录):

<div class="container">
  <button>Toggle</button>
  <div class="content">...</div>
</div>

<div class="container overflow-hidden">
  <button>Toggle</button>
  <div class="content">...</div>
</div>

.container {
  border:solid 1px red;
  position:relative;
  resize:horizontal;
}

.overflow-hidden {
  overflow:hidden;
}

button {
  position:absolute;
  top:-20px;
}

我不知道如何解决这个问题,所以如何有一个可以显示溢出项目的可调整大小的容器(可能只有 CSS) ?

要使 resize 正常工作,元素需要溢出而不是可见,所以答案是

  <div class="overflow-hidden">
    <div class="content">
      WITH "overflow:hidden":
      <br> "resize" feature is available <strike>but pulled-up button is obviously semi-hidden</strike>
