css, height of nested flexbox not correct in Chrome

Question

I have tried to create a basic layout using nested flex boxes. The layout looks fine in IE 11, but the height of the nested flex box is not being set in Chrome.

I have an example here http://jsfiddle.net/jkristia/bL4pyg4b/3/

What am I missing to get this working on Chrome ?

<div>
    <!-- header outside flex box -->
    <header class="titlebar">
        <div class="left">This is the left box</div>
        <div class="center">This text is centered in the middle box</div>
        <div class="right">Right box</div>
    </header>
    <!-- flex box -->
    <section class="flexContainer">
        <!-- row using inner flex box -->
        <div class="flexRow">
            <div class="flexContainer02">
                <div class="left">left</div>
                <div class="center">
                    <div class="flexContainer03">
                        <div class="top">center of this div.
                            <br />top</div>
                        <div class="bottom">bottom</div>
                    </div>
                </div>
                <div class="right">right</div>
            </div>
        </div>
        <div class="footer">row 3, this is the footer</div>
    </section>
</div>

and the css

Answer 1

a colleague found the solution in this codepen http://codepen.io/JosephSilber/pen/HqgAz

The problem was that I had an extra 'div' for each sub container. The solution is to mark the flex item as a new container by setting display: flex.

I have fixed my jsfiddler example http://jsfiddle.net/jkristia/bL4pyg4b/4/

html, body {
	background-color: wheat;
	width: 100%;
	height: 100%;

	height: 40px;
	background-color: #ec7fed;
	display: flex;
	flex-direction: row;

	.titlebar .left {

		border-color: white;
		border-width: 1px;
		background-color: #78c6f3;
		/* 
		below is to vertically center the text.
		Set the line height to height of parent element - any padding
	*/
		line-height: calc(40px - (5px + 5px));
		padding: 5px;
		margin-left: 10px;
		margin-right: 10px;
	}

	.titlebar .center {
		background-color: lightgreen;
		text-align: center;
		/* flexgrow allows for the box to take the remaining space in the flax container*/
		flex-grow: 1;
	}
