Hello World!

Hello World!

Welcome to the world of HTML! HTML stands for HyperText Markup Language and it is the standard markup language used for creating web pages. It allows you to structure content

add headings

paragraphs

images

links

and more. Lets dive into a simple "Hello World" example to get started.

The basic structure of an HTML document consists of opening and closing tags. Tags are enclosed in angle brackets (<>) and usually come in pairs. The opening tag denotes the beginning of an element

while the closing tag denotes the end. Heres what a basic HTML document looks like:

<!DOCTYPE html>

<html>

<head>

<title>Hello World!</title>

</head>

<body>

<h1>Hello World!</h1>

</body>

</html>

The <!DOCTYPE html> declaration at the beginning tells the browser that this is an HTML5 document. The <html> tag is the root element of an HTML page. Inside it

we have the <head> tag which contains meta information about the document

such as the title. The <body> tag is where the visible content of the web page is placed.

The <h1> tag represents a heading. It is one of six heading tags available in HTML

with <h1> being the highest level and <h6> being the lowest. Headings are used to define the structure of the webpage

and they should be used in a hierarchical order.

Save the HTML code above in a file with a .html extension

and open it in a web browser. You should see a page with the title "Hello World!" and a heading that says "Hello World!". This is the simplest example of an HTML page.

HTML provides a wide range of tags and attributes to structure and style your content. You can also include CSS (Cascading Style Sheets) and JavaScript to enhance the look and functionality of your web page. Learning HTML is the first step towards becoming a web developer

so keep practicing and exploring the possibilities that HTML offers!

Thats all for our introduction to HTML and the "Hello World" example. I hope you found it helpful and informative. Happy coding!
