What is HTML (HyperText Markup Language)?

HTML (HyperText Markup Language) is the standard markup language used for creating and structuring web pages. It is the foundation upon which websites are built. HTML uses a set of markup tags to describe the layout, structure, and content of a webpage.

HTML is not a programming language, but rather a markup language. This means that it does not have the ability to perform calculations or execute complex logic. Instead, HTML is used to define the structure and appearance of a webpage, and it is interpreted by web browsers to render the page to the user.

Basic Concepts of Web Page Structure

To understand HTML, it is important to grasp some basic concepts of web page structure. These concepts form the building blocks of any HTML document:

1. Elements: HTML documents consist of elements, which are represented by tags. Tags are used to define the structure and content of different parts of a webpage. For example, the <p> tag is used to define a paragraph, the <h1> tag is used to define a heading, and the <img> tag is used to insert an image.

2. Attributes: Attributes provide additional information about an HTML element. They are specified within the opening tag of an element and can modify the behavior or appearance of that element. For instance, the <a> tag (anchor tag) can have the href attribute to specify the destination URL for a hyperlink.

3. Nesting: HTML elements can be nested inside other elements. This allows for the creation of hierarchical structures within a webpage. For example, a <ul> tag can contain multiple <li> tags (list items) to create an unordered list.

4. Document Structure: An HTML document follows a specific structure. It typically includes an opening <html> tag, which indicates the beginning of the HTML document, followed by a <head> tag for metadata and a <body> tag for the actual content of the webpage.

5. Semantic Elements: HTML5 introduced a set of semantic elements that give meaning to the content they contain. For example, the <header> element represents the introductory content of a webpage, while the <nav> element represents the navigation section.

Understanding these basic concepts will provide a solid foundation for creating and understanding HTML documents. HTML allows web developers to structure web content in a clear and logical manner, enabling browsers to interpret and display web pages accurately.
