--description--

HTML5's audio element gives semantic meaning when it wraps sound or audio stream content in your markup. Audio content also needs a text alternative to be accessible to people who are deaf or hard of hearing. This can be done with nearby text on the page or a link to a transcript.

The audio tag supports the controls attribute. This shows the browser default play, pause, and other controls, and supports keyboard functionality. This is a boolean attribute, meaning it doesn't need a value, its presence on the tag turns the setting on.

Here's an example:

<audio id="meowClip" controls>
  <source src="audio/meow.mp3" type="audio/mpeg" />
  <source src="audio/meow.ogg" type="audio/ogg" />
</audio>

Note: Multimedia content usually has both visual and auditory components. It needs synchronized captions and a transcript so users with visual and/or auditory impairments can access it. Generally, a web developer is not responsible for creating the captions or transcript, but needs to know to include them.

--instructions--

Time to take a break from Camper Cat and meet fellow camper Zersiax (@zersiax), a champion of accessibility and a screen reader user. To hear a clip of his screen reader in action, add an audio element after the p. Include the controls attribute. Then place a source tag inside the audio tags with the src attribute set to https://s3.amazonaws.com/freecodecamp/screen-reader.mp3 and type attribute set to "audio/mpeg".

Note: The audio clip may sound fast and be difficult to understand, but that is a normal speed for screen reader users.

--hints--

Your code should have one audio tag.

assert($('audio').length === 1);

Your audio element should have a closing tag.

assert(
  code.match(/<\/audio>/g).length === 1 &&
    code.match(/<audio.*>[\s\S]*<\/audio>/g)
);

The audio tag should have the controls attribute.

assert($('audio').attr('controls'));

Your code should have one source tag.

assert($('source').length === 1);

Your source tag should be inside the audio tags.

assert($('audio').children('source').length === 1);

The value for the src attribute on the source tag should match the link in the instructions exactly.

assert(
  $('source').attr('src') ===
    'https://s3.amazonaws.com/freecodecamp/screen-reader.mp3'
);

Your code should include a type attribute on the source tag with a value of audio/mpeg.

assert($('source').attr('type') === 'audio/mpeg');
