Answer 2

& lt; body background = "img / image.jpg" width = "100%" height = "100%" & gt;

Answer 3

It is important not to forget to put quotes: background: url ("img / image.jpg") , otherwise on screens with some resolution a “strip” may appear at the bottom – the uppermost part of the background image is lowered.
