What Does HTML Do and Why Do You Need to Use It?

We’ve all heard the name, but what does HTML do? Why do we need it? And why is it important to learn at least the basics? We take a look at the answers.


The entire internet is built with HTML as its backbone. HTML code basically makes up the structure of the digital world.

Even though it is an important part of the online world, people still wonder, “what does HTML do?”

Most web pages are made with HTML. While the language is as old as the internet, it has gone through many generations. Many websites are still using HTML4, but HTML5 provides developers with more tools to work with.

HTML stands for “hypertext markup language.” The first part of that phrase refers to the thing that makes the internet what it is – hyperlinks. These are links, just like the one above, which users click on to view other HTML documents. The ‘markup’ part of the phrase just means that the file can be seen in a web browser.

There’s more to it than just that. Keep reading to see how HTML built the internet.

HTML Organizes Information so You Can Read It

The most important thing to understand about HTML is that it does not actually do anything. Other languages like Javascript or C# allow programmers to write functions. Programs written in those languages take data and do stuff with it.

HTML, on the other hand, never does anything with data. All it does is organize it in a way people can understand. Rather than developers changing data with their programs, they move around boxes where data can go.

Those boxes are displayed on a computer screen. If the developer did their job correctly, it should be easy to read the information on it. Without HTML, this website would just be endless lines of text with no organization.

That doesn’t mean developers can’t do a lot with HTML. It’s a powerful language that can be used to create amazing websites with a single HTML 101 lesson.

HTML Links Different Documents

HTML is responsible for organizing the information on your screen. It is also responsible for getting that information in the first place.

Most of the power behind websites come from separate files that HTML fetches. Javascript files can process user information and animate the website. PHP files allow the server to communicate with the browser in different ways.

There are a ton of different kinds of programs developers may use and write to support their creations. All those different files need to be fetched somehow. That’s where HTML comes in.

Beyond organizing how information is displayed, HTML also signals when information needs to be processed. It can then take that information and run it through a different program.

After that, it can display the results like any other piece of data.

You Should Still Be Asking, “What Does HTML do?”

There is so much more to HTML. With the introduction of HTML5, there is also a lot of work to do on the internet as a whole. Websites need to be rebuilt to be more organized and up-to-date. Developers have new parts of the language to learn.

You should continue to ask yourself, “what does HTML do?” because it means you want to learn more. The things that are new for the rest of us are simply matter-of-fact to you. That’s a good thing, it gives you a leg up on the rest of us.
