For some reason, a white edge has appeared down the side of my website. It was never there before. The web suggested I should make sure to reset margins etc to 0 at the top of my stylesheet, which I already do. The edge is not due to a margin or padding, since I can't select it in the Chrome developer console.
The strange this is that this sometimes removes itself when viewed through Chrome, but is always there when viewed via a mobile. (In widescreen there is white space either side so you only notice this on a small screen).
Can someone help?
