I'm having trouble centering my tumblr.
Ive tried playing with the margin and adding <center> but nothing works.
It either messes everything up or does nothing at all.
Can someone help me please?

My tumblr is DaysofDean.tumblr.com

Thanks!

See http://www.w3.org/Style/Examples/007/center.html .

But correct the errors before you add more to it.
