How to remove gray background from html tags Follow

File | Settings (Preferences for Mac OS) | Editor | Colors&Fonts | HTML | Tag -> "Save as", then you can change the background.

I tried and have no success then i post here
i'm right there but it doesn't disappear

HTML colors settings are now broken (https://youtrack.jetbrains.com/issue/WEB-13867)

I see no Save As option. I'm on a Mac.

the button is not there in recent versions - a copy of predefined scheme is created automatically once you edit the colors, so there is no need to save a scheme as a new one explicitly
