'How to add autoplay and a loop to a Youtube video on HTML?

I'm having trouble with adding autoplay to the video I want to put on my HTML site. Adding ?autoplay=1 or &autoplay=1 didn't work. -- same with the loop

<div class="videoContainer">
    <iframe class="videoContainer__video" width="560" height="315" src="https://www.youtube.com/embed/HWl8XAOQnTg?rel=0&amp;controls=0&amp;showinfo=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen> </iframe>
</div>

Not relying on parameters that don't seem to work for me – working workaround for September 2018 (bonus: set width and height by CSS for #yt-wrap instead of hard-coding it in JS):

<div id="yt-wrap">
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <div id="ytplayer"></div>
</div>

<script>
  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      width: '100%',
      height: '100%',
      videoId: 'VIDEO_ID',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
    player.mute(); // comment out if you don't want the auto played video muted
  }

  // 5. The API calls this function when the player's state changes.
  //    The function indicates that when playing a video (state=1),
  //    the player should play for six seconds and then stop.
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.ENDED) {
      player.seekTo(0);
      player.playVideo();
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
</script>

Here use this: OPEN THE BELOW CODE PEN LINK It will loop your video too : (Runs the cached version of video, look upon @Turnip Comment)

;&autoplay=1;&loop=1;&playlist=HWl8XAOQnTg

<iframe class="videoContainer__video" width="560" height="315"     src="https://www.youtube.com/embed/HWl8XAOQnTg?rel=0&amp;&amp;showinfo=0;&autoplay=1;&loop=1;&playlist=HWl8XAOQnTg"> </iframe>

Autoplays and loops on mute, works for phones and all browsers in 2022. Not all my code just different bits I pirated from other smart people. Just put in your own video id

<!-- 1. The <iframe> (video player) will replace this <div> tag. -->
<div class="iframe-container">
  <div id="player"></div>
</div>
<script>
  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      width: '100%',
      videoId: 'YOgtEDP5mlE',
      playerVars: { 'autoplay': 1, 'playsinline': 1, 'rel': 0, 'loop': 1, 'autopause': 0 },
      events: {
        'onReady': onPlayerReady,
'onStateChange':onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
   event.target.mute();
    event.target.playVideo();
  }
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.ENDED) {
      player.seekTo(0);
      player.playVideo();
    }
  }
</script>

<style>
/* Make the youtube video responsive */
  .iframe-container{
    position: relative;
    width: 100%;
    padding-bottom: 56.25%;
    height: 0;
  }
  .iframe-container iframe{
    position: absolute;
    top:0;
    left: 0;
    width: 100%;
    height: 100%;
  }
</style>
