Bonus: MonoKai Pro & Live Server

MonoKai Pro is personally one of my favorite themes to apply when writing code on VS Code since it is elegant and colorful while eliminating distractions and helps to focus on writing more code.

Live Server is another really helpful extension, helping you to actively launch a development server with automatic reloads for static and dynamic web pages.
