Responsive card component with on click hide and reveal JS feature

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

I am proud of figuring out the javascript solution pretty easy and fast. I would like to try a JS framework like Svelte and recreate the challenge.

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

The tooltip css was quite tricky and the svg styling as well

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

I would like some comments about how I could simplify the tooltip css or other methods than mine.
