Understanding HTML Tags and Elements

If you’ve ever looked at a webpage and wondered why a headline is big, why paragraphs line up neatly, or how an image sits beside text—the answer always starts with HTML.

HTML (HyperText Markup Language) is the skeleton of every webpage. CSS is the skin and clothing. JavaScript is the brain and muscles. But HTML is what gives a webpage its structure.

These are called:

They act like single-use instructions.

HTML elements don’t all behave the same. Some force a new line; some sit inside text.

This foundation is what makes CSS, JavaScript, and modern frameworks finally make sense.
