HTML is used to create and structure web pages and web applications. It provides the foundational layout and organization of content on the internet. Here are some specific uses of HTML:

1. Structuring Web Content: HTML uses tags to define different types of content on a page, such as headings, paragraphs, lists, images, links, and forms. This gives structure and meaning to the content, making it readable for users and interpretable by web browsers.

2. Embedding Media: HTML supports embedding various media, including images, audio, and video. HTML5 introduced specific tags for this purpose, like <img>, <audio>, and <video>, allowing for seamless media integration on web pages.

3. Creating Links: HTML enables the creation of hyperlinks using the <a> tag. These links connect different web pages or sections within the same page, forming the interconnected structure of the World Wide Web.

4. Defining Layout: With the help of tags like <div>, <header>, <footer>, <section>, and <nav>, HTML provides a basic layout for web pages. CSS (Cascading Style Sheets) is often used alongside HTML to refine the visual design, but HTML provides the framework for how elements are organized.

5. Interactivity with Forms: HTML supports the creation of forms using tags like <form>, <input>, <button>, and <textarea>, allowing users to submit data to a web server. This is essential for interactive features, like user registration, login, and data collection.

6. SEO and Accessibility: HTML’s semantic tags (like <article>, <header>, <footer>) help search engines and screen readers understand content structure, improving search engine optimization (SEO) and making websites more accessible to users with disabilities.

In short, HTML is essential for building, organizing, and structuring the content and functionality of web pages.
