HTML, or HyperText Markup Language, serves as the backbone of web development, providing the essential framework for creating and structuring content on the internet. It is a markup language that allows developers to define the structure of web pages through a series of elements and tags. Each HTML document is composed of a hierarchy of elements that dictate how content is displayed in a web browser.

Understanding this structure is crucial for anyone looking to create effective and accessible web pages. The fundamental building blocks of HTML are its tags, which are enclosed in angle brackets. These tags can define everything from headings and paragraphs to links and images.

The organization of these tags within a document follows a specific syntax that ensures browsers can interpret and render the content correctly. As web technologies have evolved, so too has HTML, with HTML5 introducing new elements and attributes that enhance the language’s capabilities, making it more versatile for modern web applications.

Understanding HTML Tags and Elements

HTML tags are the core components that make up an HTML document. Each tag serves a specific purpose, and they often come in pairs: an opening tag and a closing tag. For instance, the `

` tag is used to define a paragraph, with `

` marking the beginning and `

` indicating the end.

This structure allows browsers to understand where content begins and ends, facilitating proper rendering on the screen. Additionally, some tags are self-closing, such as the `` tag, which does not require a closing counterpart. Elements in HTML consist of the opening tag, content, and closing tag.

For example, in the element `

Welcome to My Website

`, “Welcome to My Website” is the content that will be displayed as a top-level heading on the page. Attributes can also be added to tags to provide additional information or modify their behavior. For instance, the `` tag, which creates hyperlinks, can include an `href` attribute that specifies the URL to which the link points.

Understanding how to effectively use tags and elements is essential for creating well-structured and functional web pages.

Importance of Semantic HTML

Semantic HTML refers to the use of HTML markup that conveys meaning about the content it contains. This approach enhances accessibility and improves search engine optimization (SEO) by providing context to both users and search engines about the nature of the content. For example, using `
