HTML, or HyperText Markup Language, is a fundamental building block of the World Wide Web. It serves as the
standard markup language for creating and structuring content on webpages. Developed by Tim Berners-Lee in 1991, HTML has evolved over the years and plays a crucial role in shaping the digital landscape we navigate today.
What is HTML?
HTML is a markup language that uses a system of tags to annotate text, images, and other multimedia elements within a document. These tags define the structure and presentation of content on a webpage. HTML documents are plain text files with a .html extension, and they can be created and edited using any simple text editor.

A typical HTML document has a basic structure consisting of a head and a body:
htmlCopy
code
<!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <!-- Content goes here --> </body> </html>
·
<!DOCTYPE
html>: This declaration
specifies the document type and version of HTML being used (in this case,
HTML5).
·
<html>: The root element that wraps the entire HTML
content.
·
<head>: Contains meta-information about the document,
such as the title and links to stylesheets.
·
<title>: Sets the title of the webpage, which appears
in the browser tab.
·
<body>: Houses the main content of the webpage.
HTML Tags:
HTML tags are used to
mark elements within a document, and they are enclosed in angle brackets. Some
common HTML tags include:
·
<h1>
to <h6>: Headings of different
levels.
·
<p>: Paragraph.
·
<a>: Anchor for hyperlinks.
·
<img>: Image.
·
<ul>: Unordered list.
·
<ol>: Ordered list.
·
<li>: List item.
·
<div>: Division or section.
·
<span>: Inline container.
Attributes:
HTML tags can have
attributes that provide additional information about the element. For example:
htmlCopy
code
<a href="https://www.example.com" target="_blank">Visit Example.com</a>
·
href: Specifies the hyperlink destination.
·
target="_blank": Opens the link in a new browser tab.
Document Structure and Nesting:
HTML elements can be
nested within one another, creating a hierarchical structure. For instance:
htmlCopy
code
<div> <h1>Main Title</h1> <p>This is a <em>paragraph</em> with emphasis.</p> </div>
HTML5 and Semantic Markup:
HTML5 introduces
semantic elements like <header>, <nav>, <article>, <section>, and <footer>. These tags enhance the structure of a webpage,
making it more accessible to both developers and assistive technologies.
Conclusion:
HTML serves as the backbone of the web, providing the structure
necessary for browsers to render content. It is the first step in web
development, forming the foundation upon which CSS (Cascading Style Sheets) and
JavaScript build to create dynamic and visually appealing websites.
Understanding HTML is essential for anyone entering the field of web
development, and it continues to be a vital skill in the ever-evolving digital
landscape
