Answer 1

It depends on if you mean from a developer's or designer's perspective. As a developer, you should at least take the html, css, and javascript courses here. Then you'll understand how to create a website as you want. As a designer, you'll need to learn about layouts and other design aspects, and learn what makes a functional and visually appealing website. In either case, you'd be better off studying both. Knowing one makes the other easier.
