Actually at first, as I'm using my phone, I must say that Codepen mobile UX is great. There are three buttons on top that act as tabs. There are no visible scrollbars on phones, there are no visible scrollbars in Codepen. They either programmed that or conformed to the OS, the result is OK.
I switched to desktop mode to get the HTML and result views side by side. I have to horizontally scroll the page but that's to be expected on a narrow screen. There is no visible scrollbar but again, that could be because of the mobile OS. If I were on my laptop with a full screen window I wouldn't mind to have an always visible OS scrollbar at the right of the HTML editor. It's in the middle of the screen but I've got OS scrollbars in the middle of the screen any time I place an editor window to the left of my screen, so what's the problem?
