In addition of my previous question to edit the breakpoint for change the menu to mobile menu, I noticed something else.
In desktop mode it works correct, but on my ipad pro there is a difference between pages. As can see on the first screenshot, it al fits on the screen, responsiveness does his job.
But on the second screenshot, the content doesn't fit. Maybe it has to do with the menu. (also notice the very small icon on the left in the menu, which is the logo. It also has the wrong size. On my desktop the logo isn't there)
