CSS height 100% in firefox not working

Question

I have the following HTML and CSS that behaves totally different in Firefox and Chrome.

JSFiddle.

.container {
  width: 200px;
  height: 50px;
  border: 1px solid black;
  display: inline-table;
}

.content {
  background-color: red;
  width: 30%;
  height: 100%;
}

<div class="container">
    <div class="content"></div>
</div>
<div class="container">
    <div class="content"></div>
</div>

In Chrome it displays correctly but not in Firefox.

Chrome:

Firefox:

By inspecting the content div in Firefox, the height is 0.

Why does it work in Chrome and Safari, but not in Firefox? I notice that removing the display: inline-table will work but the container div will be stacked instead of inline.

Answer 1

Try changing display: inline-table; to display: inline-block;.

Answer 2

I could only get it to work when I used

.content {
    display: inline-table;
 }
