Intro component with signup form using Sass

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

Quite happy with how it turned out:

• Learnt that event listener getting attached to input fields, remain active even after the submit event has completed since event listeners are attached to the DOM element, not just limited to the scope of the event handler.
• Was going to add animation but got bored by the end of it
• Ended up with very structured code I feel and used BEM convention
