I have just started something and I cannot resolve an issue. So far I have just one page plus a css file.
The page had a full screen image as a background, this works find in 'standard' screen maode and 'full' screen mode, but if I reduce the screen with the 'reduce down' button, the top of the background image appears at the bottom of the page.
For some reason I don't seem to be able to upload the code to this post, so I;ve saved it as an image.

We don't use absolute positioning for vertical centering anymore. With CSS Grids, there's less code and none of the consequences that come from positioning elements absolutely.
