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

What I am most proud of is the java script is mostly written without any help. Needed help with the math but the rest was put together with just the knowledge I have learned so far. What I would do differently next time is all of the css. I need to focus on better class and id names. And grouping things so I don't have to write so much code.

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

The biggest challenge was getting the colored boxed inside the inputs. The placement was very difficult and the boxes would go outside the borders of the input boxes. The only way I knew how to get the box inside the input was absolute placement and margins. Learned a technique to hide the input borders and use the div element to make a border.

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

My css is a struggle. One part of this project I could not fix no matter what I tried was when numbers typed in the input boxes the background of the input turns light blue. I could not find the fix to it.
