Almost finished portfolio page. Looking for feedback/help

Ive basically finished the page. however, I cant seem to get my contact form to resize when I make my browser smaller. Also, Whenever I click one of the navigation anchors, it turns blue which is really annoying. I have hover, visited, active etc all using the same color but I cant figure out how to change that.

Aside from that though, Im just looking for general feedback on my code to see if I could do anything better, more efficiently, etc. Thanks!
