What's new in HTML5?

[Qomplainerz]

1. Semantic elements:

HTML5 introduces many new semantic elements that help describe the structure of the content better, making it easier for search engines and screen readers to understand the page's purpose. Some key semantic elements include header, nav, main, article, section, footer, aside, etc.

2. Multimedia:

HTML5 provides built-in support for audio and video without the need for plugins like Flash. 
The audio and video elements allow embedding media directly into the page.

Example:

Code:

<audio controls>
  <source src="audio.mp3" type="audio/mpeg">
  Your browser does not support the audio element.
</audio>

Code:

<video controls width="640" height="360">
  <source src="video.mp4" type="video/mp4">
  Your browser does not support the video element.
</video>

3. Form enhancements:

HTML5 enhances form handling with new input types, validation attributes, and the datalist element for autocomplete suggestions.

Example:

Code:

<input type="email" required>
<input type="date">
<input type="range" min="0" max="100">
<input type="color">
<input type="search" list="search-suggestions">
<datalist id="search-suggestions">
  <option value="Keyword 1">
  <option value="Keyword 2">
</datalist>

4. Canvas:

The canvas element allows dynamic rendering of graphics, charts, animations, and games using JavaScript. 
It provides a 2D drawing context and, with WebGL, can even support 3D graphics.

5. Offline web applications:

HTML5 includes an Application Cache feature that enables web applications to work offline and load faster by storing resources locally. 
This is achieved using the manifest attribute in the html tag.

6. Geolocation:

HTML5 supports geolocation, allowing websites to access the user's location through the Geolocation API.

7. Web storage:

HTML5 introduces Web Storage (localStorage and sessionStorage) to store data locally on the user's browser for a more extended period compared to cookies.

8. Web workers:

Web Workers allow running JavaScript code in the background without interfering with the page's responsiveness, enabling multi-threading.

9. Drag and Drop:

HTML5 provides native support for drag-and-drop interactions, making it easier to implement intuitive UI elements.
