HTML is at the core of every web page, regardless the complexity of a site or number of technologies involved. It's an essential skill for any web professional. It's the starting point for anyone learning how to create content for the web. And, luckily for us, there's not too much to learn about it. HTML stands for HyperText Markup Language. "Markup language" means that, rather than using a programming language to perform functions, we use tags to identify different types of content and the purposes they each serve to the webpage.
CSS stands for Cascading Style Sheets. This programming language dictates how the HTML elements of a website should actually appear on the frontend of the page. If HTML is the drywall, CSS is the paint. Whereas HTML was the basic structure of your website, CSS is what gives your entire website its style. Those slick colors, interesting fonts, and background images? All thanks to CSS. This language affects the entire mood and tone of a web page, making it an incredibly powerful tool - and an important skill for web developers to learn.
