Compatibility Mode in Internet Explorer 9
The above screenshot was taken with compatibility mode turned on in IE 9. Having compatibility on turns your modern browser into Internet Explorer 7 which does not have the capability of utilizing modern technologies.
Below is what the page should look like.
If you're noticing display issues when using IE 9, click on the blue icon in the browser address bar, which looks like a torn piece of paper. Once you click on it, it will turn gray, which means compatibility mode is off and it should correct any display issues.
