So we added the option to have a fixed width on a page. Note that if you do this, you want have the same options as before in terms of background and stripe. You can have groups, floating groups, etc. but they won’t go to the edge of the screen.
If you want to do this, make the page responsive, and simply have a group that has a fixed width and put all elements inside. Again, this will lead to exactly the same result as before.
