This one is a little tricky because there are two syntax for audio.
Here src is an attribute of the audio element.
<audio src="horse.ogg" controls>
Your browser does not support the audio element.
</audio>
Here source is a separate element with a src attribute.
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio tag.
</audio>
