Hi, I'm new to the forum and am very much hoping I can get some help with a slight issue I am having with some Tumblr HTML I am trying to code! The last week or so I've been learning HTML and I have tried my hardest to try use floats and inlines properly to allow my divider positions to work as intended.

This is my code: http://jsfiddle.net/cqu5ruyg/

I think it's quite clear what needs to be done, but just in case it's not, I need the 'post' division to stay centered with the header, and the 'sidebar' division to stay at the left. The issue is when resizing the window, the 'post' division will move to the bottom instead of create scroll bars and stick to the center like I need it to. The 'sidebar' division will also squish up which I don't think it's meant to either.

I hope someone can provide some help as it would be extremely appreciated! Many thanks smile.gif
