This is basic stuff and im quite new to this but can someone explain the difference between styles using # and . and ones without. I can't find any basic sites explaining it and its just totally confusing me at the mo!!?
And how from a linked external css file can you get all the page margins to zero or do you have to do that in the actual page?
Im also looking to have a constant footer at the base of my page say 40px tall but when i put it in it lines up completely differently to the rest of the page?
Thanks for any help
