Is it possible to make a very little space (even if it is 1mm) between the last line in the page and the number of the page?. For sure, I need to do this for all pages not only for one page. Note that I’am using \documentclass{article} and I provide
\usepackage{geometry}
\geometry{footskip=15pt}
Here is a screenshot of how the bottom of the pages looks like. Your help is greatly appreciated.
The question in other words: Is it possible to get the number of the page slightly down ?!

\geometry{footskip=1mm}should do it. However don't forget some letters have descenders (g, p,q,y, italic f), so 1mm might be a little just. – Bernard Nov 13 '16 at 20:28
