A Beginner's Guide to HTML5: Building the Foundation of the Web
HTML5 (Hypertext Markup Language 5) is the latest version of the HTML standard used for creating and structuring content on the web. It introduces new features and improvements that enhance the way web pages are developed, making them more interactive and responsive. Here are the basics of HTML5:
Document Structure: HTML5 documents have a simple structure. They start with a
<!DOCTYPE html>declaration, which tells the browser that the document is written in HTML5. The content of the document is enclosed within
<html>tags, and it's divided into two main sections:
<html> <head> <!-- Meta information, title, linked stylesheets, etc. --> </head> <body> <!-- Content visible on the web page --> </body> </html>
Semantic Elements: HTML5 introduces a set of semantic elements that provide meaning to the structure of a web page. These elements help search engines and assistive technologies understand the content better, and they also make the code more readable for developers. Some common semantic elements include

<h6>represents the lowest. Regular text is wrapped in paragraphs using the
<h1>Main Heading</h1> <p>This is a paragraph of text.</p>

<form action="/submit" method="post"> <input type="text" name="username" placeholder="Username"> <input type="password" name="password" placeholder="Password"> <button type="submit">Submit</button> </form>
Audio and Video: HTML5 provides
<video>tags to embed audio and video content directly in the web page.
<audio controls> <source src="audio.mp3" type="audio/mpeg"> Your browser does not support the audio element. </audio> <video controls> <source src="video.mp4" type="video/mp4"> Your browser does not support the video element. </video>
<link rel="stylesheet" href="styles.css"> <script src="script.js"></script>
