I was doing the same when I had it in the body, so I took the footer out of the body thinking that mibght top it conflicting with the body rules but to no avail…
Others have solved the problem you came in with, but a couple of points (if you will pardon the phrase) … don’t use points.
A point is a physical measurement of 1/72 inch. It only makes sense to use points for print stylesheets where there is a physical measurement that can be made. Screen displays don’t work like that. The actual size will depend on the screen size and resolution, so it makes no more sense to say that you want 30pt of padding than it does to set the width of a box to 5cm.
For screen stylesheets, you can use em, % or px but not pt, cm or in. (And even if you could use pt, you would put “8pt”, not “8 point”)
