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. Let's 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. Here's 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!
That's all for our introduction to HTML and the "Hello World" example. I hope you found it helpful and informative. Happy coding!
