Responsive and Interactive Time Tracking Dashboard with vanilla JS

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

This is the first time I have fully implemented designs for all the screen-widths from 320px to 2560px.

For next time, I will try to build my projects more efficiently, where instead of completing everything in one main.css page; I could add more pages or even complete the CSS more methodically.

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

I encountered an issue that I later discovered was just a chrome-devtool issue. Basically, there was a hairline border across all the time tracking containers that was doing my head in. I have now realised that it isn't an issue upon deployment...

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

Would love feedback on how to write more efficient Javascript! I originally began coding with Java, so I am not sure if my style of writing Java code is most efficient or practical when writing Javascript. Anything thoughts, queries or criticism helps, thanks in advance!
