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

I used to use single CSS style for all my files, While using dev tool i found out that the element were render multiple times. so i don't know but i used that css file to my main app, which remove the bug of rendering same style multiple times. I don't know if i am right or wrong , i don't have enough clue to understand how it works and what is the best practice to be like one of professionals.

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

• I encounter the style to be rendered multiple times. So i overcome that by using css in my main app only.
