HTML stands for HyperText Markup Language and comes in second place on our list of most popular coding languages of 2021. As mentioned before, HTML is a front-end web development language. As it is a Markup Language, HTML is responsible for formatting the appearance of information on a website. HTML is limited to creating and structuring text on a website since its job is to describe web pages through ordinary text. Headings, links, paragraphs, and titles are all the work of HTML. A great example of an HTML text editor is WordPress.

While it is more focused on formatting than other coding languages, HTML still plays a crucial role in website functionality. It helps that HTML is also relatively easy to learn. A wide variety of resources and guides are available in forums and through videos on YouTube.

When used in conjunction with JavaScript and HTML, it can provide a smooth and intuitive user experience.

Learning CSS isn’t any more difficult compared to JavaScript or HTML. There are plenty of online learning resources, as well as a healthy community to seek advice from. As a complete kit, JavaScript, HTML, and CSS will make you a well-rounded developer.
