Thanks for your input. Yes, but I don't really know how to fix it. I mean we could add a guideline for future rules (and update the existing ones) to always use `max-width 45em` or the like for text instead of `100%`, whenever possible. That would complicate things quite a bit though, currently it's as easy as it gets...
I am also not super sold on capping max width. My personal take is, if text gets unreadable for you on a 27 inch screen, then don't buy a 27 inch screen, or at least resize the browser window accordingly. I haven't grasped yet why anyone would want to have a large widescreen display/window for reading text, I think it's only counterproductive.
That is admittedly a rather egoistic take though, and insane screen resolutions are seemingly becoming the norm now, so I don't know what to do.
