On the <audio> tag, add the proper type attribute that corresponds to the source file. What am I doing wrong?

<audio src="http://treehouse-code-samples.s3.amazonaws.com/html-video-and-audio/bridge-audio.mp3" type="bridge-audio.mp3"/>

that's my own code. why does it has to be "audio/mp3"? PLEASE HELP.

<!DOCTYPE html>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <h1>HTML Video and Audio</h1>

    <div class="wrapper">

      <!-- Add your code below this line -->
     <audio src="http://treehouse-code-samples.s3.amazonaws.com/html-video-and-audio/bridge-audio.mp3" type="bridge-audio.mp3"/>



it has to be type="audio/mp3" as what that is doing is telling the html what type of file format the mp3 audio file is. Same would go for if you're doing videos it would be type="video/mp4"

Hi Sev,

First of all, your original answer was really close. Like all other HTML syntax rules, browsers require the "type" attribute to be in a specific format. The "type" attribute within an <audio> tag tells the browser what file extensions you're using. So, browsers need all developers to declare that attribute in a standardized way. Here's a link to the W3C standard on how they recommend adding sources to an audio tag: https://www.w3schools.com/TAGS/tag_audio.asp

It looks like you already figured out the answer: <audio src="http://treehouse-code-samples.s3.amazonaws.com/html-video-and-audio/bridge-audio.mp3" type="audio/mp3" />
