Is there any way to have text formatted to center on mobile while keeping it right or left justified on desktop?

Just as stated in the title - on desktop view I have blocks that have a photo with text arranged next to it and the text is either right or left justified depending on where the photo is. Is it possible to have that text center justified on mobile so that it looks less clunky, without affecting the desktop organization? This is super frustrating.

Also wondering if I can remove a section on mobile view without removing it from desktop view.

Thanks for any help.

Yes and yes. Both with Custom CSS.

Can you share your website URL and the blocks you want the text centered and the section you want hidden on mobile?
