i.e and ff

Been using html to make a website (just teaching myself as much as i can) but after doing it all and viewing it through firefox my mate said look at it through i.e and it looks different. This seems a common thing which i never knew just wanting some advice or a point in the direction to see if i can solve the problem!

Any help greatly appreciated

There's lots of things that IE handles differently than FF or any legitimate browser. I'd suggest using google searches to research and playing with CSS to learn how to properly design for both.
