Contact Form "Black Boxes" in IE8 - Weird Issue

I created a contact form that seems to be working fine in all browsers except IE8 and older. On those browsers, black boxes appear over the input field areas and make them so text can not be inputted.

I’m having a hard time testing it as I don’t have IE on my Mac, but I was able to quickly confirm the error was happening on a friends laptop.

Any ideas?

The inline CSS has invalid colour values for the border if using hexidemal your INPUT style attribute ‘color’ should be written: #256632 not 256632 it is missing the “#” symbol.
