General domain of usage  
Web development

**Tags**, **elements**, and **attributes** are the core building blocks of every HTML page. You'll explore each of them in detail later. For now, you're getting familiar with the basics.

Important

## Tags
Tags define elements in an HTML document. They are written inside angle brackets: `<tag>` and `</tag>` (opening + closing). The content between them is what the element contains. For example, `<p>...</p>` defines a paragraph.

## Elements
An element = opening tag + content + closing tag. Elements can contain text or other nested elements. For example, `<p>I am a paragraph.</p>`, this is the complete HTML element.

## Attributes
Attributes give extra information about an element. They appear inside the opening tag as `name="value"`. They can change the element's behavior or appearance. For example, `<img src="image.jpg" alt="Image" />`, `src` sets the image URL and `alt` provides fallback text.
