Webstorm gives strange green background in html file

Question

Okay sorry for the little bit big picture (problem is my retina screen I guess). Not sure how to set width in stackoverflow.

But my question is, if I make a html file in webstorm some of the back ground is green, and I don't understand why and I find it kind of ugly, so I would wish to make this back ground just normal. Is there some option where I can do this ?

Answer 1

I needed to uncheck this. I'm not sure why or how this got in, doesn't seem to be standard.
