CSS: fixed to bottom and centered

Question

I need my footer to be fixed to the bottom of the page and to center it. The contents of the footer may change at all time so I can\'t just center it via margin-left: xxpx;

Answer 1

The problem lies in position: static. Static means don't do anyting at all with the position. position: absolute is what you want. Centering the element is still tricky though. The following should work:

#whatever {
  position: absolute;
  bottom: 0px;
  margin-right: auto;
  margin-left: auto;
  left: 0px;
  right: 0px;
}

or

#whatever {
  position: absolute;
  bottom: 0px;
  margin-right: auto;
  margin-left: auto;
  left: 50%;
  transform: translate(-50%, 0);
}

But I recommend the first method. I used centering techniques from this answer: How to center absolutely positioned element in div?
