Hi there @fecso!
Given that there are no built-in options for what you describe, you’ll need to use some custom CSS code. Providing it is outside of scope of our support though.
For customization of this type, I recommend collaborating with a developer locally or with someone from our customizations page https://woocommerce.com/customizations/.
Just in case, you can read through this short guide to get more comfortable with CSS code and be able to make some changes even yourself:
