and so with some research, I've put together the following JavaScript: Ok, so the final hurdle in what for me would be a perfect solution is for any screen res lower than 1000px - currently the horizontal scroll bar is removed - therefore the central page has its right potentialy chopped off. I began working on a "best" solution for screen res widths of 1024+ for centralised fixed width pages with potentialy large (or any size) left and right margin graphics and have come up with something I'm very happy with:Īn outside wrapper set to 100% + overflow hidden (removes the horizontal scrollbar on all screen res)Ī wrapper inside that set to 1000px with margin auto (allows the central page to be in the middle of, or to fill the page of all screen res - brilliant because originally one main objective was for a left margin not to push the page to the right and out of view on a lower res screen)Īn inside wrapper inside the centralised one above set to for example, width 1800px and left 400px, allows both margins to be viewable for all screen res larger than the central page (1000px+) Can anyone help please, it would be greatly appreciated! This works completly fine in 1280 x 800 but goes mental when you hover over it in 1024 x 768 screen resolution.
