How to remove blank white space below footer?

I tried to eliminate the white space according to the answered questions that I found. But not of them is working on my side.

I tried to remove the padding in div's footer, but still the white space still there.

How to fix this?

CSS:

Solution

Your code shows nothing, perhaps you can't reveal your web address no problem. You need to check something in your html any div or content area have minus value like top:-100px if you set something like this you need to change like margin-top:-100px
