Introduction to HTML

 Introduction to HTML :


HTML stands for HyperText Markup Language. 

HyperText refers to the ability to link to other documents or web pages using hyperlinks. 
Markup Language means using tags to organize and format content on a web page.
So, HTML is a language that uses tags to structure content and connect web pages through links.

It is the standard language used to create and design web pages. HTML uses a system of tags to structure content, such as headings, paragraphs, links, images, and more.

HTML is not a programming language; it is a markup language for structuring content.

HTML is the basic building block of a web page.


 *History of HTML

1989-1991: HTML was invented by Tim Berners-Lee at CERN (European Council for Nuclear Research) to help researchers share documents.

1993: The first official HTML specification was published.

1995: HTML 2.0 was released, standardizing early features.

1997-1999: HTML 3.2 and 4.01 introduced more elements and better structure.

2014: HTML5 became the latest standard, adding multimedia support and new semantic elements.


 *Features of HTML

Simple Syntax: Easy to learn and use.

Platform Independent: Works on all operating systems and browsers.

Hyperlinks: Allows linking between web pages.

Multimedia Support: Can embed images, audio, and video.

Forms: Supports user input through forms.

Semantic Elements: Provides meaning to content (e.g., `<header>`, `<footer>`, `<article>`).

Extensible: Can be combined with CSS and JavaScript for styling and interactivity.


 *Limitations of HTML

Presentation: Limited styling and layout capabilities without CSS.

Logic: Cannot perform programming logic or dynamic content without JavaScript.

Security: Vulnerable to code injection if not used carefully.

Browser Differences: Some tags and features may not work the same in all browsers.

Static Content: HTML alone cannot create interactive or dynamic web applications.


Basic Structure of a HTML page :

The basic structure of an HTML page includes the following elements:


<!DOCTYPE html>
<html>
  <head>
    <title>Page Title</title>
  </head>
  <body>
    <!-- Page content goes here -->
  </body>
</html>

Explanation :

`<!DOCTYPE html>`: Declares the document type and version of HTML.

`<html>`: Root element of the HTML document.

`<head>`: Contains meta-information like the title and links to stylesheets.

`<title>`: Sets the title of the web page (shown in the browser tab).

`<body>`: Contains the visible content of the web page.


Every HTML page must contain the above elements.
