Recipe page using html and css

What are you most proud of, and what would you do differently next time?

I am not very proud of my work this time.

What challenges did you encounter, and how did you overcome them?

This one was difficult especially that I didn't have the Figma file. It also requires the use of a variety of html elements like lists and tables which I'm not comfortable using yet.

What specific areas of your project would you like help with?

I would like to receive help in three areas:

1. How can I make the list bullets and numbers colorful? I didn't know what selector to use.
2. How do I make borders between border rows? (except for the last row?)
3. I am getting a little bit confused about when to use specific units of measurement. When should I use relative units, percentages, and pixels? If someone can briefly explain it to me..
