Introduction to HTML

HTML, which stands for Hypertext Markup Language, is the backbone of web development. It is a markup language used for creating and structuring sections, paragraphs, and links on web pages. Every web page you visit is built using HTML. It lays the groundwork for web design and web content, which can be further styled by CSS and made interactive with JavaScript.

What Are HTML Tags?

HTML tags are the basic building blocks of HTML. They define and structure the content of a web page by enclosing different parts of the content to make it function in a certain way or to format it to look a specific way. Each tag is made up of elements surrounded by angle brackets, like <tagname>content</tagname>. Tags usually come in pairs, though some are self-closing.

For example, the <p> tag is used to create a paragraph:

<p>This is a paragraph in HTML.</p>

Understanding Attributes

Attributes provide additional information about HTML elements. They are always specified in the start tag and usually come in name/value pairs like name="value". For example, to set the width of an image, you would write:

<img src="image.jpg" alt="Description of the image" width="500">

In this example, src, alt, and width are attributes of the <img> tag.
