HTML tags are the building blocks of web pages. They are used to create elements that define the structure and presentation of web content. Each tag serves a specific purpose, such as displaying text, creating links, or embedding images and videos. Understanding these tags is crucial for anyone looking to build or modify a website.

HTML tags serve as the foundation upon which all web pages are built. They provide the basic framework that web browsers use to display content. Each tag tells the browser how to interpret and display the enclosed content, ensuring that text, images, and other elements appear correctly on the screen.

HTML tags come in various forms, each with its specific function. There are structural tags that define the overall layout of a page, formatting tags that control the appearance of text, and interactive tags that enable user interaction. Familiarity with these types allows developers to choose the right tags for their needs.

Using the correct HTML tags is not just about structure; it’s also about semantics. Proper tag usage enhances accessibility, SEO, and the overall user experience. For instance, using heading tags correctly helps search engines understand the hierarchy and importance of content, which can improve search rankings.
