I have a problem with the mobile view of my site where the header and prefooter extend way out from where the page ends.
If you minimise the browser you can see it when you scroll across, and I have a screenshot where you can see the prefooter extending out - also only 3 of the 4 images appear across the page, though I am assuming that's about the size of the images.
Another forum topic mentioned changing the header pixels to em, but that only messed up the desktop version and didn't change the mobile one.
I'm sorry if it's obvious and I've just missed it. Any help to fix this is very welcome!
