What is HTML?

HTML stands for HyperText Markup Language. It is the standard markup language for creating web pages and applications. HTML describes the structure and content of a web page, using tags to define Elements like headings, paragraphs, images, and links.

How HTML Works

HTML documents are plain text files that contain tags enclosed in angle brackets (< and >). These tags tell the web browser how to display the content.

Example:

“`html

div class="telegram-channel-container"> Join Our Telegram Channel

html>


My Web Page

Welcome to my website!

This is a paragraph of text.


“`

In this example, <h1> defines a heading, <p> defines a paragraph, and <title> defines the title that appears in the browser tab.

Basic HTML Elements

Here are some of the most common HTML elements:

Element Description Example
<h1> to <h6> Heading elements, used for titles and subtitles <h1>Main Heading</h1>
<p> Paragraph element, used for blocks of text <p>This is a paragraph.</p>
<a> Anchor element, used for creating links <a href="https://www.example.com">Link to Example</a>
<img> Image element, used for embedding images <img src="image.jpg" alt="Image description">
<ul> and <li> Unordered list elements, used for creating lists with bullet points <ul><li>Item 1</li><li>Item 2</li></ul>
<ol> and <li> Ordered list elements, used for creating lists with numbers <ol><li>Item 1</li><li>Item 2</li></ol>
<table> Table element, used for creating tables <table><tr><td>Cell 1</td><td>Cell 2</td></tr></table>

provide additional information about HTML elements. They are written within the opening tag and consist of a name-value pair separated by an equals sign (=).

<img src="image.jpg" alt="Image description" width="200" height="100">

In this example, src, alt, width, and height are attributes.

HTML Structure

HTML documents have a basic structure:

  • <!DOCTYPE html>: Declares the document type as HTML.
  • <html>: The root element of the document.
  • <head>: Contains metadata about the document, such as the title and links to external Resources.
  • <title>: Specifies the title of the page, which appears in the browser tab.
  • <body>: Contains the visible content of the web page.

Semantic HTML

Semantic HTML uses elements that describe the meaning of the content, rather than just its appearance. This makes the code more readable and understandable for both humans and machines.

Example:

Instead of using <div> for a section of content, use <ARTICLE> if it represents a self-contained article.

HTML5

HTML5 is the latest version of HTML, released in 2014. It introduces new elements, attributes, and APIs, making it more powerful and versatile. Some key features of HTML5 include:

  • New semantic elements: <article>, <aside>, <nav>, <footer>, etc.
  • Multimedia support: <audio> and <video> elements for embedding audio and video.
  • Canvas API: For drawing graphics and animations.
  • Web Storage API: For storing data locally on the user’s computer.

CSS and JavaScript

HTML is often used in Conjunction with CSS (Cascading Style Sheets) and JavaScript. CSS is used to style the appearance of HTML elements, while JavaScript adds interactivity and dynamic behavior.
