Discover how to build your website by learning HTML and CSS on your Mac. It's pretty easy to get started with web coding in OS X, and there are plenty of great courses to help you learn HTML and CSS. CotEditor is a relatively new and fresh development for everyone who doesn’t need.
HTML5 is built-in to Safari, it may depend on the website you are accessing on whether it is used. For YouTube you may need to first visit the following URL to 'turn on' HTML5 for YouTube.
When HTML5 was new Safari was one of the better web-browsers in terms of supporting it, however sadly it seems that Apple have neglected this and according to some reports have not kept up with newer changes in the HTML5 spec. This should not prevent playing (most) HTML5 video content though.
You can test HTML5 video support here - http://www.quirksmode.org/html5/tests/video.html
You can test HTML5 general compatibility here - https://html5test.com/index.html even Safari 10 scores much lower than the current Google Chrome and Firefox browsers. 😟
Safari only supports H.264 and does not support OGG/Theodora or WEBM however H.264 is far, far more common and is what YouTube and Netflix use as examples.

Another nice feature from the HTML5 draft specification is now available in the WebKit nightly builds for Mac OS X. The new HTML5 <video> and <audio> elements add native support for embedding video and audio content in web pages. They also provide a rich scripting API for controlling playback. Adding video to a web page is almost as simple as adding an image:
<video src=sample.mov autoplay></video>
Html5 For Mac Os Versions
To make a button that gives the user basic playback controls you could do this:
<script>
function playPause() {
var myVideo = document.getElementsByTagName('video')[0];
if (myVideo.paused)
myVideo.play();
else
myVideo.pause();
}
</script>
<input type=button value='Play/Pause'>
The specification also defines a set of events that can be used to react to changes in media playback and load state. For example:
myVideo.addEventListener('ended', function () {
alert('video playback finished')
} );
To play audio from JavaScript you can simply do this:
var audio = new Audio('song.mp3');
audio.play();
The implementation is still a work in progress and not all features (including the ‘controls’ attribute which gives native playback controls) of the specification are there yet. The current implementation supports all formats that QuickTime supports, including installed 3rd party codecs.

The example below uses the ‘poster’ attribute of the <video> element to display an initial image before the video is loaded, progress events to track loading, and play/pause/ended events to make the overlay button reflect the video’s state.
