Interactive Card Details Form made with HTML, TypeScript and Sass/Scss

One difficulty I ran into because I couldn't remember how to do it in vanilla is when you type in the input, it changes simultaneously with the preview card. One thing I'm not sure about is accessibility in the HTML structure. I guess it's not a good practice to have all the eventListeners in one file, but since it's a small project it seemed like the easiest thing to do.
