// sync progress bar on load and when seeking via keyboard video.addEventListener('seeked', () => updateTimeAndProgress(); );
Once you've added the iframe, customized the player, and added controls, you can put everything together. Here's an example of what your final CodePen project might look like: youtube html5 video player codepen
#speed-btn margin-left: 10px;
volume.addEventListener('input', (e) => video.volume = parseFloat(e.target.value); video.muted = video.volume === 0; muteBtn.textContent = video.muted ? '🔈' : '🔊'; ); .controls-right flex: auto
/* time text */ .time-text font-size: 0.85rem; font-weight: 500; color: #ddd; letter-spacing: 0.3px; font-family: monospace;
videoPlayer.addEventListener('timeupdate', () => const currentTime = videoPlayer.currentTime; const totalTime = videoPlayer.duration; const progress = (currentTime / totalTime) * 100; progressBar.value = progress; currentTimeSpan.textContent = formatTime(currentTime); totalTimeSpan.textContent = formatTime(totalTime); ); Once you've added the iframe
.progress-buffer position: absolute; top: 0; left: 0; height: 100%; background: rgba(255,255,255,0.4); border-radius: 5px; pointer-events: none; width: 0%;
