magento2 – Different CSS styles for each category page

Magento community!
Today I find myself with a task quite simple in my opinion but due to my little experience in Magento 2, I am not finding a way to apply different CSS styles for each category page.
I need to give a height of different pixels to the container that builds the banner-slider for each category of my store since in category A the image of the banner looks perfect, but in category B as well as in category C the image of the banner is overlaid by another container that is displayed below it.
Thank you! I hope that some enlightened one can help me.
