Hi guys.
I want to make a layout like this: http://imageshack.us/a/img577/3946/divlayout.png

I tried several things, but can't get it to work. It need to be responsive (so with percentages).

<div id="div1">
<img id="img1" />
<img id="img2" />
</div>

give div1 a css width of 40%, and margin: 0 auto.
And then?

Thanks in regards!!
