Time tracking page w/ data retrieval, CSS local props, JS

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

The frontendmentor article on JS eventhandling was really useful, as I learned to use the data--attribute, which made the code a lot cleaner and more efficient.

I keep getting better at dealing with elements, HTMLCollections etc in JS, but it's still not entirely clear, so need more practice w/ that.

Also, I felt the site needed a tablet layout as well, so I set up a two column layout as an intermediary between mobile and desktop.

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

I need to get more confident handling elements in JS. I keep getting confused with the different types returned by functions like getElementsByClassName etc
