I'd like to center an image (that changes dimensions according to the screen size) horizontally vertically in a div. That div is positioned absolute and has a height of 100%. Under that div, another div is placed.
I made a visual example
<body>
<div id="wrapper">
<div id="div1">
<div id="center">
<img src="http://www.vilna.nl/wp-content/uploads/2013/10/test.jpg">
</div>
</div>
<div id="div2">
You can't see this without scrolling
</div>
</div>
</body>
I want to center the test image vertically in the red div.
Thanks!
