Time tracking dashboard using HTML,CSS, JS, async-await & transition!

genuinely proud of how this one came out. only issues are:-

• how can I get rid of that annoying outline at the bottom of each container. there's a faint outline of the color of the background color behind it.
• is there a better way to decrease the size of the containers? the grid row seems to be making the containers longer and not wider. not that my solution is completely different, but it's just different from the design slightly
