Customizing the YouTube HTML5 Video Player with CodePen: A Comprehensive Guide
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); );// Helper: Format time (seconds -> MM:SS)
function formatTime(seconds)
if (isNaN(seconds)) return "0:00";
const hrs = Math.floor(seconds / 3600);
const mins = Math.floor((seconds % 3600) / 60);
const secs = Math.floor(seconds % 60);
if (hrs > 0)
return $hrs:$mins < 10 ? '0' : ''$mins:$secs < 10 ? '0' : ''$secs;
