type="audio/mpeg"><br>  <source src="audio.ogg" 
type="audio/ogg"><br></audio>

3. New Form Elements and Input Types

HTML5 enhances web forms with new input types and attributes that improve user experience and data validation.

• New Input Types: email, date, time, url, number, range, search, tel, color.
• New Form Attributes: placeholder, required, pattern, autocomplete, autofocus.

<form>
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" required>

<canvas id="myCanvas" width="400" height="200"></canvas>

<script>
  var canvas = document.getElementById("myCanvas");
  var ctx = canvas.getContext("2d");
  
  ctx.fillStyle = "green";
  ctx.fillRect(10, 10, 150, 100);
</script>

5. Local Storage and Offline Capabilities

HTML5 introduces nearby storage alternatives that allow internet programs to store data on the person’s device, enhancing performance and allowing offline get admission to.

• local storage: It stores records with no expiration date.
• session storage: It stores date for the duration of the session.
• Application cache: It allows applications to run offline by caching resources.

Example:

// Store
localStorage.setItem("username", "JohnDoe");

// Retrieve
var username = localStorage.getItem("username");
console.log(username);

6. Geolocation API

The Geolocation API permits web applications to get entry to the person’s geographical region, furnished the user presents permission. This function is beneficial for place-based services like maps and weather apps.

Example:

<button onclick="getLocation()">Get Location</button>
<p id="demo"></p>

<script>
function getLocation() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(showPosition);
  } else {
    document.getElementById("demo").innerHTML = 
    "Geolocation is not supported by this browser.";
  }
}

function showPosition(position) {
  document.getElementById("demo").innerHTML = "Latitude: " + position.coords.latitude + 
  "<br>Longitude: " + position.coords.longitude;
}
</script>

6. Web Workers

Web Workers offer a manner to run scripts in history threads, making an allowance for concurrent execution and enhancing the performance of web programs by offloading intensive duties from the primary thread.

Example:

if (window.Worker) {
  var worker = new Worker("worker.js");

  worker.onmessage = function(event) {
    document.getElementById("result").innerHTML = event.data;
  };

  worker.postMessage("Start working");
}

Content of worker.js:

onmessage = function(event) {
  var result = 0;
  for (var i = 0; i < 1000000000; i++) {
    result += i;
  }
  postMessage(result);
};

8. Responsive Design

HTML5, in conjunction with CSS3, provides features that support responsive web design, enabling web pages to adjust seamlessly to different screen sizes and devices.

• Media Queries: Allow the application of different styles based on device characteristics.

<meta name="viewport" content="width=device-width, initial-scale=1">

<style>
  body {
    font-family: Arial, sans-serif;
  }

  .container {
    display: flex;
    flex-wrap: wrap;
  }

  .item {
    flex: 1 1 200px;
    margin: 10px;
    padding: 20px;
    background: #f0f0f0;
  }

  @media (max-width: 600px) {
    .item {
      flex: 1 1 100%;
    }
  }
</style>

<div class="container">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>

Conclusion

HTML5 has notably more suitable the abilities of internet development through introducing new factors, attributes, and APIs that facilitate the advent of greater interactive, green, and consumer-pleasant internet programs.. Its functions, starting from advanced semantics to stronger multimedia help and robust offline capabilities, make HTML5 an crucial device for current internet developers. By leveraging these features, developers can construct dynamic and attractive net experiences that cater to the various needs of ultra-modern net users.
