Help needed

So, we have a .html file that says:

<div class="grayBlock">
	<div class="blueBlock">
		Very meaningfull caption
	</div>
	<div class="pinkBlock">
		<img src="path/to/a/very/nice/pic.jpg"/>
	</div>
</div>

I need the browser to render this (no need for IE trickery):

What i need is this

Can someone help with the .css file please? Very very please…

Late edit: done! All i needed was a transform-origin: bottom left; ! Ha!
