HTML, or HyperText Markup Language, is the standard markup language used to create and structure content on the World Wide Web. It forms the backbone of web pages and is responsible for defining the structure, layout, and elements within a webpage. HTML is not a programming language; rather, it is a markup language that focuses on presenting content and organizing its presentation.
Here are some key aspects of HTML:
Markup Tags: HTML uses a system of markup tags, also known as elements or tags, to define the structure and content of a webpage. These tags are enclosed within angle brackets (< >) and are typically written in pairs, consisting of an opening tag and a closing tag.
Document Structure: An HTML document typically starts with a declaration, which specifies the version of HTML being used. It is followed by an element that contains two main sections: and . The section contains meta-information about the document, such as the title, character encoding, and linked resources. The section contains the actual content visible to users.
Elements and Attributes: HTML elements represent different types of content, such as headings, paragraphs, images, links, lists, forms, and more. Each element may have attributes that provide additional information or modify its behavior. Attributes are usually specified within the opening tag and are written as name-value pairs, separated by equal signs.
Images and Media: The element is used to embed images within a webpage. HTML5 also introduced various elements for embedding multimedia, such as
Links: Hyperlinks are created using the element, which allows you to link to other web pages or resources on the Internet.
Lists: HTML supports both ordered (<ol>) and unordered (<ul>) lists, as well as definition lists (<dl>), which are used to organize items with associated descriptions.
Forms: HTML provides form elements like and <button> to create interactive input forms for user interaction.
Semantic Elements: HTML5 introduced a range of semantic elements that convey the structural meaning of different parts of a webpage, aiding in better accessibility and SEO.
Validation: HTML documents should adhere to a well-defined structure and syntax. Validating HTML ensures that the code is correctly written and follows the standards, which helps in cross-browser compatibility and proper rendering.
