Do you need to learn HTML, CSS, and JavaScript in web design when you can easily create websites with AI-powered tools? That’s a question that stopped me in the tracks because there’s no easy answer.

Still, for someone whose first taste of web design was with Macromedia Dreamweaver, I’ll say it helps to know how websites are put together.

Even if you’re creating landing pages with advanced tools like HubSpot’s AI website generator, you never know when you’ll need to manually change the font, layout, or animate a particular web element. And knowing the web fundamentals — specifically HTML, CSS, and JavaScript — definitely helps.

In this guide, I’ll walk you through each of them, explaining how each web technology works and why it’s important for developing modern websites.

HTML, CSS, and JavaScript at a Glance

Almost every modern website uses HTML, CSS, and JavaScript. The fact that you’re able to read this blog, presented in an aesthetically pleasing layout, and see a slide-in pop-up after scrolling to a certain depth is due to all three web technologies.

The best way to understand each of them is to use the house analogy.

• HTML provides structure to a website, just like how beams and pillars support a house.
• CSS beautifies an otherwise plain web page, much like paints and wallpapers enhance the beauty of a house.
• JavaScript allows users to interact with a website by adding behind-the-scenes functionality. It’s like adding plumbing, electricity, and internet to a house.

If you’re not familiar with coding, they might look similar and confusing. But when you’re trained to look into the details, or specifically the syntax and semantics of each, you’ll be able to differentiate them.

What is HTML?

HTML stands for HyperText Markup Language. It structures a web page into logical parts so the web browser knows where the header, body, paragraphs, tables, images, and other elements are. For example, these are common elements that you can specifically state in an HTML document.

• contains metadata of the web page.
• consists of visible content that users can see.

  the heading with the largest font size.

• starts a paragraph.

• bolds the text.

How does HTML work?

When you visit a webpage, the browser loads the associated HTML document from the web server. An HTML document organizes web content with a series of HTML tags. Then, the browser creates a Document Object Model (DOM), which it uses to understand how various web elements relate to each other. You can think of DOM as a building blueprint that explains a house’s structure.
