Want to learn about CSS course that is used in hybrid app dev

Hello Friends, hope you are all good & doing well.

I’m newbie here & want to know about that css code which is used in hybrid app development.
If you know about anything, whatever is video tutorials, or tool. let me know or share. i have been see YouTube tutorials but didn’t understand.

I think you should go there app development company to know about CSS code which is used in hybrid app development. It’s much better then video tutorials.
