• What are HTML Tags, Element and Attributes 

• HTML Tag

The individual component of an element's syntax, enclosed in angle brackets (e.g., <p>, </p>).

Opening Tag: <tagname>
Closing Tag: </tagname>

Common Tags: Headings, Paragraph, Image, Link

• HTML Attributes

HTML attributes provide additional information to elements (e.g., href="https://www.example.com").

Example: <img src="image.jpg" alt="A beautiful scenery">

Common Attributes: href, src, alt, class, id

• HTML Element

The complete structure consisting of an opening tag, content, and a closing tag.

Example of Elements: <h1>This is a heading</h1>

• Self-Closing Tags

Some HTML tags are self-closing, meaning they don't need a closing tag. These are also considered elements.

Example of a Self-Closing Tag: <img src="image.jpg" alt="A beautiful scenery">
