css - small margin / gap at the top of document

Question

I have come across this before a while back and forgotten what the solution was. I have a small gap at the very top of my document, maybe 5/10px?

I think you will know what I am talking about, how do i get rid of this?

Thanks

In your CSS file add this:

html, body { margin: 0; padding: 0; }
