HTML, or HyperText Markup Language, is the backbone of nearly every web page you’ve ever visited. It’s the unseen hero, laying the groundwork for the web as we know it today and serving as the foundational structure for our online universe.
But why is HTML so important? Think of a website like a house. The HTML is the house’s blueprint. It defines where the doors, windows, and walls go. Without it, you’re left with a pile of bricks, pipes, and wires — technically, all the parts of a house, but far from a livable structure.
In the realm of web development, HTML is the bedrock skill that any budding front-end developer must master. Whether you’re a hiring manager looking for the best talents, or a tech professional aiming to elevate your skill set, understanding HTML’s depth and breadth is critical.
In this article, we’ll guide you through the basics and key features of HTML as well as its advantages, use cases and place in the current tech hiring landscape.
What is HTML?
Contrary to common belief, HTML is not actually programming language. It’s a markup language, which means it’s used to structure content on the web. It lays down the foundation for web pages, allowing us to insert various types of content such as text, images, videos, and more into web pages.
HTML dates back to the early days of the web. Created in 1990 by Tim Berners-Lee, a computer scientist at CERN, HTML was initially a simplified subset of SGML (Standard Generalized Markup Language) intended to manage the hypertext documents on the World Wide Web. Over the years, HTML has evolved to become an extensive markup language with a wide range of elements and attributes, allowing for richer web content.
A web page built with HTML consists of a series of elements, defined using tags. These tags act as containers that tell your web browser how to display the content they enclose. For example, the ‘<h1>’ tag is used to define the largest heading, while the ‘<p>’ tag is used to define a paragraph.
Consider this simple HTML example:
<!DOCTYPE html> <html> <head> <title>My First Web Page</title> </head> <body> <h1>Welcome to My Web Page</h1> <p>This is a paragraph of text on my web page.</p> </body> </html>
In this snippet, we’ve defined a basic HTML structure. It has a `<title>` that will appear on the browser tab, an `<h1>` heading, and a `<p>` paragraph in the `<body>`. When opened in a web browser, this HTML file will display a web page with a heading and a paragraph of text.
Over the years, new versions of HTML have been released. At time of writing, HTML5 is the latest major version. Each new version introduces additional elements and attributes, offering more flexibility and capability to web developers around the globe.
The core principle, however, remains the same: HTML is the cornerstone of many web pages, and its mastery is a must-have skill for anyone working on the web.
Key Features of HTML
HTML is deceptively simple, yet profoundly powerful. It’s this range of capabilities, packaged in an approachable syntax, that makes HTML a key player in web development. Let’s dive into some of its main features.
Tags and Elements
As mentioned earlier, the building blocks of HTML are tags. They surround and apply meaning to content. When a start tag, some content, and an end tag are combined, they form an element. For example, `<p>Hello, world!</p>` creates a paragraph element containing the text “Hello, world!”
Attributes provide additional information about HTML elements. They come in pairs: a name and a value. The name is the property you want to set, and the value is what you’re setting it to. For instance, in `<img src=”image.jpg” alt=”A beautiful sunrise”>`, “src” and “alt” are attributes providing additional information about the image element.
Hyperlinks and Images
One of the most powerful features of HTML (and the web in general) is the ability to link to other web pages. This is done using the anchor tag `<a>`. For instance, `<a href=”https://www.example.com”>Visit Example.com</a>` creates a clickable link to example.com.
Similarly, images are embedded using the `<img>` tag. The source of the image file is specified in the ‘src’ attribute, like so: `<img src=”image.jpg”>`.
Forms and Input
HTML allows for user input through forms, making interactive web pages possible. Forms can contain input elements like text fields, checkboxes, radio buttons, and more. For instance, `<input type=”text”>` creates a text input field.
Here is a simple form example:
<form action="/submit_form" method="post"> <label for="fname">First Name:</label><br> <input type="text" id="fname" name="fname"><br> <input type="submit" value="Submit"> </form>
This form contains a text input field and a submit button. When the user clicks the submit button, the form data is sent to the ‘/submit_form’ URL for processing.
These are just a few of the many features HTML offers. By combining these elements and attributes, developers can create a complex, interactive web page that serves virtually any purpose. In the hands of a skilled developer, HTML is a tool of endless potential.

Advantages of Using HTML
HTML is not the only technology used for building websites, but it is one of the most critical and universal. Its enduring popularity among web developers can be credited to several key advantages.
HTML was designed with accessibility in mind. The correct usage of HTML tags helps define content structure and hierarchy, which is used by assistive technologies such as screen readers to accurately interpret the page content. Tags like `<header>`, `<nav>`, `<main>`, and `<footer>` provide semantic meaning to content, making a website more accessible to all users.
Search Engine Optimization
Search engines like Google depend on HTML structure to understand and rank content. Properly used HTML tags help to clearly delineate the important parts of a web page, such as titles and headers, improving a website’s visibility in search engine results.
Ease of Learning and Use
One of the most significant advantages of HTML is its simplicity. Compared to many other languages, HTML is relatively straightforward to pick up, even for beginners. Its syntax is logical, and you can see the results of your code immediately in a web browser, providing instant feedback that aids learning and debugging. Moreover, you don’t need any special software to write HTML — a simple text editor is enough.
Wide Support and Compatibility
Common Use Cases for HTML
