HTML (Hypertext Markup Language) is the standard markup language for creating web pages and applications. It consists of a series of elements, which you can use to structure content on a web page. Each element has a specific purpose and a distinct role in the document. Here are some key components:
HTML Tag: The building block of HTML. Tags are used to denote the start and end of an element. For example, <p> starts a paragraph and </p> ends it.
Element: An element comprises a start tag, content, and an end tag. For instance, in <h1>Hello World</h1>, <h1> is the start tag, "Hello World" is the content, and </h1> is the end tag. Together, these form the "h1" element.
Attributes: Elements can also have attributes, which provide additional information about the element. Attributes are defined within the start tag. For example, <a href="https://www.example.com">Link</a>; here, href is an attribute of the <a> tag.
Nested Elements: HTML allows elements to be nested within other elements. This creates a parent-child relationship in the DOM (Document Object Model). For example, <ul><li>List Item</li></ul>; here, the <li> element is nested inside the <ul> element.
Void Elements: Some elements don't have an end tag and don't contain content. They are self-closing. For example, <br> for a line break, and <img src="image.jpg"> for an image.
Doctype Declaration: An HTML document begins with a doctype declaration <!DOCTYPE html>, which tells the browser to render the page in HTML5 mode.
Head and Body: The <head> element contains meta-information about the document, like its title and links to stylesheets, while the <body> element contains the content of the document that's visible to users, such as headings, paragraphs, images, hyperlinks, tables, lists, etc..
HTML is a key foundational technology for web development and understanding its structure and usage is crucial for creating effective and interactive web pages.
