You’re not encouraging anyone to help you with that kind of attitude.
You didn’t mention Stylish until someone asked..if you had then maybe we would have understood what it was you were asking.
As for your specific problem…it’s not much help posting what code you have because we don’t know how it relates to Google’s HTML.
I’m not familiar with Stylish but I imagine that it has ‘toggles’ so that you can turn the overrides on and off?
If so..start toggling…apparently something you did made the logo disappear..then you should be able to find out what it was and undo it.
Other than that…use Developer Tools (inspect element) that come with your broswer (f12) to see what CSS is applied to the logo. You can turn specific CSS properties on an off and find the source of the issue there.
