So ive been on the graphic design industry for over a year growing on my own(haven't taken any education on it) and I was looking for forum that might help me keep growing and I found this.

I was looking for some help building a website i got the design all finished but my web programming is awful I was looking to build a website that when you click a link the whole page doesnt have to reload instead just reloading the content only, I know its possible but I was wondering if someone can point me in the right direction. Thank You

What I got so far: http://coastalpropertyinc.com/

This is just my concept not the finished website(Most links are dead).
Working links are the houses on the left, notice how the page reloads after clicking each link?
