Hi @writetoyogen,

I'm really sorry but this requires custom CSS coding and it depends on different dynamic conditions, this is not a stable color and doesn't have a simple solution. Please note, that we don't provide support for style customization, we may help in 1-2 simple questions related to colors and background but not more. We can not help you customize all components of forum style, these are custom requirements and should be done by forum owners. We only help in general questions and issues.

Thank you for your understanding.

Thankyou for informing. I'll try to fix.

However, it would be much easier if you could direct me to CSS documentation or just inform me what class and containers defines which sections...

You can find all classes by pressing F12 on browser and opening Chrome or Firefox Console:
