Extending position absolute div outside overflow h

问题:

I've haven't done css in several month so I might miss something simple, but whatever the solution is, I couldn't figure it out. So here is the problem.

Here is simplified version of my code:

<div id="wrapper" style="position: fixed; overflow: hidden; height: 100%; width: 200px;">
  <div id="test" style="position: absolute; margin-left: -200px;"></div>
</div>

So basically, I need the inner div test to extend 200px to the left, outside of outer div wrapper. The problem is that my wrapper is overflow:hidden and it won't allow to go outside. I need it to stay overflow:hidden though, due to some js plugin I am using.

So is there any workarounds? Thanks

回答1:

Only option is to move that div outside of the overflow:hidden div. You can't say hide everything in this div that overflows -- except for this one div... let's make an exception.

You can introduce one more layer in your hierarchy, whereby the inner div is overflow hidden and the outer div is not. Then place that positioned element in the outer div. A pseudo example would be:

<div class="outer">
  <div class="inner" style="overflow: hidden;">
    ....
  </div>

  <div class="abs-positioned">
  </div>
</div>

If by chance you had positioning on the old div with overflow:hidden, you would move that setting to the outer div, allowing things to position properly.

So the short answer: no solution will allow you to do what you want without either changing your CSS to not be overflow:hidden or without changing your markup.

Expanding on Piyas De:

an example

Do note, that if the overflow hidden has

position: relative

then it will not work

回答3:

Overflow hidden can actually be ignored if the following rules are observed:

• The overflowing child element has absolute positioning
• The parent with overflow hidden has static positioning
• A second parent wrapper with relative positioning is added

HTML

<div class="outer-wrapper">
  <div class="wrapper">
    <div class="overflowed">(Overflowing the wrapper)</div>
  </div>
</div>

CSS

.outer-wrapper {
  position: relative;
}
.wrapper {
  overflow: hidden;
}
.overflowed {
  position: absolute;
}

Something like -

<div id="textChange" style="overflow:hidden; padding-left:250px;">This is wrapper Div
This is wrapper Div<br/>
This is wrapper Div<br/>
<div id="textChange1" style="position:absolute;left:50; top: 50;">
This is inner div but extend 200px to the left<br/>
This is inner div but extend 200px to the left<br/>
This is inner div but extend 200px to the left<br/>
This is inner div but extend 200px to the left<br/>
This is inner div but extend 200px to the left<br/>
</div>
This is wrapper Div<br/>
This is wrapper Div<br/>
This is wrapper Div<br/>
</div>

May solve your problem.

See..whether it helps or not...

Here's a fix that does not requires Javascript or moving anything. Just add a Parent wrapper with the width and height of #wrapper.

<div id="parent_wrapper" style="width:200px">
  <div id="wrapper" style="position: absolute; overflow: hidden; height: 100%; width: 300px;">
    <div id="test" style="position: absolute; margin-left:200px;">Test</div>
  </div>
</div>
