Dasmoto's Art and Craft's

As I created the website I was not confident that I could do it. But I took some deep breaths and told myself I could. and I did it I built the website. I learned that there are more efficient ways of creating the site. I compared my code to the Codecademy code. I noticed I added more CSS. The outcome was similar but I learned that my code isn’t as efficient as the code from Codecademy.

How can I make more clean code and have many IDs and classes within my HTML?
