CSS Styles don't work in IE

Hi Everyone,

I am new to CSS and coding actually. I am having trouble with my CSS working in IE. It works in FF, Opera, Safari but not IE8.

I'm sorry if my code is messy! I am still learning.

I did a css validation and took on the recommendations.

Thanks in advance.

Well, you could start by not making up elements.

Thank you.. it was doing my head in. I'm embarrassed it was such a silly mistake!
