What is HTML?
HTML (Hypertext Markup Language) is the standard markup language used for creating and structuring content on the web. It defines the structure of web pages using a system of tags and elements, allowing browsers to interpret and display text, images, links, and other media.
Key Features of HTML
Structure: HTML provides a framework for organizing content. It uses elements like headings, paragraphs, lists, and tables to create a clear layout.
Markup Language: Unlike programming languages, HTML is a markup language that describes the content's structure rather than implementing logic or algorithms.
Tags and Elements: HTML uses tags (enclosed in angle brackets) to denote different types of content. Tags usually come in pairs: an opening tag (e.g.,
<p>) and a closing tag (e.g.,</p>).Attributes: Tags can include attributes that provide additional information about an element. For example, the
hrefattribute in an anchor tag (<a>) specifies the URL of the link.Semantic HTML: This refers to using HTML elements that convey meaning about the content they contain (e.g.,
<header>,<footer>,<article>,<section>). Semantic elements enhance accessibility and SEO.
Basic Structure of an HTML Document
Here’s a simple example of an HTML document structure:
__________________________________________________________________
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First Web Page</title>
</head>
<body>
<h1>Welcome to My Web Page</h1>
<p>This is a paragraph of text on my first web page.</p>
<a href="https://www.example.com">Visit Example</a>
</body>
</html>
Key Components Explained
<!DOCTYPE html>: Declares the document type and version of HTML being used (HTML5 in this case).
<html lang="en">: The root element of the HTML document, with the
langattribute indicating the language.<head>: Contains meta-information about the document, such as its title and character set.
<title>: Sets the title of the web page, displayed in the browser's title bar or tab.
<body>: Contains the main content of the page, including text, images, links, and other elements.
Conclusion
HTML is the foundational language for web development, allowing developers to create structured and accessible web content. Understanding HTML is essential for anyone looking to build websites or engage in web design and development.
