Heading One

This is my text for heading one. Is everything going to be under heading one?

Column one is right here and will be purple. I don't think I'm doing this right.

Heading Two

Nope. I'm going to put something in heading two.

Column two is here and is going to be orange. I forgot this needed to be two sentences so I went back and put one in.

Column three! I guess I'll make this column blue. Blue and orange are complimentary colors.

Heading Three

Can't forget my external link.
