Newsletter challenge using TailwindCss and Javascript

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

Finally getting my first project using javascript. I managed to get things working but i really don't know how to be honest. my hope is with time and more projects it will begin to make more sense.

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

Struggling with javascript to be honest as there seems to be so many ways to achieve the same goal and its hard to know the best way. Im also struggling with using tailwind with javascript. I find it hard to find solutions online when i encounter problems.

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

I would love to know what others use to link the html to the javascript when working with tailwind css as i find with all the classes you add with tailwind it makes more sense to get it with an id but you can only have one id and numerous class names. what is the common practise amongst developers using Tailwind css?
