White Background in Editor Issue

Help
#1

Hi guys. I just started learning D3 yesterday and my editor looked more like what Curran’s did in this video https://www.youtube.com/watch?v=WoJxanRe06k&list=PL9yYRbwpkykvOXrZumtZWbuaXWHvjD8gi .

But now it’s got this weird white background on it that I don’t know how to revert to the original format:

Does anybody know how to fix this (make the white go away)?

Whoah that’s wild! I’ve never seen that before. What browser and operating system are you using?

Try in Chrome.
