For comprehensive coverage of these concepts, see the Learn Frontend Development in 180 Days ebook.

Core Multimedia Implementation

        <source src="presentation.mp4" type="video/mp4">
        <source src="presentation.webm" type="video/webm">
        <track src="captions.vtt" kind="captions" srclang="en">
        <p>Download the <a href="presentation.mp4">video file</a></p>
    </video>
</div>

Key features from our Frontend Development ebook:

2. Accessible Audio Player

<audio controls preload="metadata">
    <source src="podcast.mp3" type="audio/mpeg">
    <source src="podcast.ogg" type="audio/ogg">
    <p>Access the <a href="transcript.txt">podcast transcript</a></p>
</audio>

Complete Production Example

<!DOCTYPE html>

Hey Dhanian, I'm Ramkumar Baghel from India, and I'm currently diving deep into frontend development. I've already mastered HTML, CSS, JavaScript, and Tailwind CSS, and I'm gearing up to explore React.js next. I also have solid experience working with GSAP for animations.

I'd love to collaborate with you—maybe we can build a portfolio together and sharpen our skills along the way. Let’s create something great!
