Well maybe you need glasses because the original post was:
Why isn’t my footer at the bottom?
I guess if you want to add redundant code, go ahead. Because as I stated, if the footer is the last item to be placed in the html document there’s no need to use any code at all.
Redundancy is good for many things, coding isn’t one of them.
I should know, I have a lot of it I still need to get rid of.
