If you're taking a dive into web development, you're bound to come across the term HTML5. It's the fifth and the latest version of the Hyper Text Markup Language (HTML), the code that describes web pages. HTML5 has a ton of new features, APIs, and elements that make web applications more powerful and user-friendly. So let's dive in to explore some of the key features of HTML5!

New Semantic Elements

HTML5 introduced a bunch of new semantic elements that allow you to describe the type of content contained within them. They provide a more precise understanding of the page structure to both the programmer and the browser.

<header>
<nav>
<main>
<article>
<aside>
<footer>

These tags give us a more logical layout and better document readability. They also help in improving the search engine optimization.

Multimedia Elements

HTML5 has made the web a more vibrant place by making it easier to include and handle multimedia and graphical content on the web without having to resort to proprietary plugins and APIs. The <audio> and <video> tags allow you to embed media directly into your web pages.

<video src="movie.mp4" controls>
    Your browser does not support the video tag.
</video>

Web Storage

Another powerful feature of HTML5 is the introduction of web storage which is more secure and faster compared to cookies. Moreover, it allows storing a large amount of data without affecting the website's performance. Web storage is split into two types: localStorage and sessionStorage.

localStorage.setItem("lastname", "Smith");
document.getElementById("result").innerHTML = localStorage.getItem("lastname");

Canvas and SVG

HTML5 brought in native support for 2D drawing with the <canvas> element and Scalable Vector Graphics (SVG). This has opened a whole new world for web-based games and apps that require dynamic, interactive graphics.

<canvas id="myCanvas" width="200" height="100"></canvas>

APIs Galore

HTML5 has a plethora of APIs that have made web applications more interactive and user-friendly. These include Geolocation API, Drag and Drop API, Application Cache API, and many more. These APIs have significantly broadened the capability of web applications, making them more powerful and versatile.
