If you want captions, adaptive streaming (HLS/DASH), thumbnail preview on hover, or a mobile-specific layout, tell me which feature and I’ll extend the CodePen example.

/* The Video Element */ .video-element width: 100%; height: auto; display: block; cursor: pointer;

Use elements for controls and ensure they have aria-label attributes for screen readers.

By building this yourself on CodePen, you gain complete control. You aren't stuck with YouTube's API limitations or ads. You own the player.

<div class="controls" id="controls" aria-hidden="false"> <button id="play" class="btn" aria-label="Play (k)">►</button>
