That’s right. The styles of content A and content B overlap. What I want to achieve is: content A uses the style of content A, and content B uses the style of content B without interfering with each other. Thank you

Because the style of content A is more important, I hope you can help me modify the style of content B instead of modifying the style of A. Thank you

Hero, I left a message for you, please take a look, or add me QQ 77644278, it may be clearer to take a screenshot in QQ for you, thank you!

@calmcrime
Hero, or you can make the code into an HTML file and you can see what is going on.

If you have any questions, just ask here and post a screenshot
