Child inside parent with min-height: 100% not inheriting height

Question

Add height: 1px to parent container. Works in Chrome, FF, Safari.

This is a reported webkit (chrome/safari) bug, children of parents with min-height can't inherit the height property: https://bugs.webkit.org/show_bug.cgi?id=26559

Apparently Firefox is affected too (can't test in IE at the moment)

Possible workaround:

• add position:relative to #containment
• add position:absolute to #containment-shadow-left

The bug doesn't show when the inner element has absolute positioning.

Edit on April 10, 2014

Since I'm currently working on a project for which I really need parent containers with min-height, and child elements inheriting the height of the container, I did some more research.

First: I'm not so sure anymore whether the current browser behaviour really is a bug. CSS2.1 specs say:

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

If I put a min-height on my container, I'm not explicitly specifying its height - so my element should get an auto height. And that's exactly what Webkit - and all other browsers - do.

Second, the workaround I found:

If I set my container element to display:table with height:inherit it acts exactly the same way as if I'd give it a min-height of 100%. And - more importantly - if I set the child element to display:table-cell it will perfectly inherit the height of the container element - whether it's 100% or more.

Full CSS:

html, body {
  height: 100%;
  margin: 0;
}

#container {
  background: green;
  display: table;
  height: inherit;
  width: 100%;
}

#content {
  background: red;
  display: table-cell;
}

The markup:

<div id="container">
  <div id="content">
      <p>content</p>
  </div>
</div>

See http://jsfiddle.net/xrebB/54/.

thought I would share this, as I didnt see this anywhere, and is what I used to fix my solution.

SOLUTION: min-height: inherit;

I had a parent with a specified min height, and I needed a child to also be that height.

.parent {
  min-height: 300px;
  background-color: rgba(255,255,0,0.5); //yellow
}

.child {
  min-height: inherit;
  background-color: rgba(0,255,0,0.5); //blue
}

p {
  padding: 20px;
  color: red;
  font-family: sans-serif;
  font-weight: bold;
  text-align: center;
}

<div class="parent">
  <div class="child">
    <p>Yellow + Blue = Green :)</p>
  </div>
</div>

This way the child now acts as height 100% of the min-height.

I hope some people find this useful :)

This was added in a comment by @jackocnr but I missed it. For modern browsers I think this is the best approach.

It makes the inner element fill the whole container if it's too small, but expands the container's height if it's too big.

#containment {
  min-height: 100%;
  display: flex;
  flex-direction: column;
}

#containment-shadow-left {
  flex: 1;
}

Kushagra Gour's solution does work (at least in Chrome and IE) and solves the original problem without having to use display: table; and display: table-cell;. See plunker: http://plnkr.co/edit/ULEgY1FDCsk8yiRTfOWU

Setting min-height: 100%; height: 1px; on the outer div causes its actual height to be at least 100%, as required. It also allows the inner div to correctly inherit the height.
