unless what you are talking about is you want the “body” and “backround”, etc, to have different colors.
That ability has never existed in the HTML/PHP/ASP parser as far as I am aware, so if that is what you were wanting, it doesn’t yet exist. For example, here’s similar code in the HTML parser of v8.3.3:

I now assume that what you’re wanting is for it to render the style similar to the way CSS is highlighted, but just inside the <style> tag in the HTML or PHP (or similar):

That would require a feature request, because we fellow users in the Community forum cannot add features to the codebase. Further, I don’t think a feature request for Notepad++ will be sufficient: Notepad++ uses the Scintilla Lexilla lexer for handling the syntax highlighting, so I believe you would have to convince Scintilla/Lexilla to add CSS highlighting inside their HTML/PHP/ASP parser, and they would have to implement it, then you would have to lobby the Notepad++ developers to update to the newer version of Scintilla that contains the updated parser.
