Sidebar Pushed Thin in IE

IE handles margins/padding differently. It looks like your page is handling it very gracefully, frequently when you an image that size (encroaching into sidebar) it will shove it to the bottom of your page…

If you want it to look the ‘same’ for IE, I would recommend you use the conditional comment https://www.maratz.com/blog/archives/2005/06/16/essentials-of-css-hacking-for-internet-explorer/
and call another css file just for IE (copy current one to ie.css, for example), adjusting margins/padding there for IE only.

Nice looking site, btw.
