Vertical Align variable height elements in fixed width container - html

Question

Using display:table;, I am trying to vertically align two inline div's with different heights inside a fixed width container.
display:table; and display:table-cell with vertical-align: middle; is a very simple solution to this that works in certain circumstance - however in this it seems I have missed something.
The result of my fiddle is a correct vertical-align however each element is not holding their responsive widths to fill the entire container space. i.e. 2 elements inside the container equal 50% width.
Here is my code:
HTML
<div class="table container">
<div class="inner-column table-cell">
<div class="table inner-container">
<div id="left" class="table-cell">
content
</div>
</div>
</div>
<div class="inner-column table-cell">
<div class="table inner-container">
<div id="right" class="table-cell">
content
</div>
</div>
</div>
</div>
CSS
body {
width: 100%;
margin: 0 auto;
background: white;
color: white;
text-align: center;
background: white;
}
.table {display: table;}
.table-cell {display: table-cell; vertical-align: middle;}
.container {
width: 600px;
height: 200px;
background: lightgrey;
margin: 0 auto;
white-space: nowrap;
padding: 0
}
.inner-column {
display: inline-block;
white-space: normal;
width: 50%;
height: 100%;
border:1px blue solid;
padding: 0;
margin: 0;
}
.inner-container {
margin: 0 auto;
width: 100%;
}
#left {
background-color: red;
height: 120px;
}
#right {
background-color: purple;
height: 170px;
}
Here is the above in a FIDDLE
Problem List:
Width of the inner-column is slightly bigger than the container
each element container is not vertically aligned to the fixed height of the container.

Answer 1

display:table-cell is not being applied since you wrote this code before display:inline-block.
