time tracking page using json for data

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

I am very proud of how I was able to reuse styles across the board. I'm also starting to like using classes for dom changes instead of inline styles.

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

I couldn't figure out how to automate the timeframe checking when a timeframe is clicked so instead I wrote the code for each timeframe individually. Any advice on how I could make this code shorter is appreciated. I also had a problem with the page in mobile size. It was overflowing in y and cutting of the top and bottom parts of the page and I don't know why.
