Test your skills: Multimedia and embedding

This aim of this skill test is to assess whether you've understood our Video and audio content and From object to iframe โ€” other embedding technologies articles.

Note: You can try out solutions in the interactive editors below, however it may be helpful to download the code and use an online tool such as CodePen, jsFiddle, or Glitch to work on the tasks.

If you get stuck, then ask us for help โ€” see the Assessment or further help section at the bottom of this page.

Multimedia and embedding 1

In this task we want you to embed a simple audio file onto the page. You need to:

  • Add the path to the audio file to an appropriate attribute to embed it on the page. The audio is called audio.mp3, and it is in a folder inside the current folder called media.
  • Add an attribute to make browsers display some default controls.
  • Add some appropriate fallback text for browsers that don't support <audio>.

Multimedia and embedding 2

In this task we want you to mark up a slightly more complex video player, with multiple sources, subtitles, and other features besides. You need to:

  • Add an attribute to make browsers display some default controls.
  • Add some appropriate fallback text for browsers that don't support <video>.
  • Add multiple sources, containing the paths to the video files. The files are called video.mp4 and video.webm, and are in a folder inside the current folder called media.
  • Let the browser know in advance what video formats the sources point to, so it can make an informed choice of which one to download ahead of time.
  • Give the <video> a width and height equal to its intrinsic size (320 by 240 pixels).
  • Make the video muted by default.
  • Display the text tracks contained in the media folder, in a file called subtitles_en.vtt, when the video is playing. You must explicitly set the type as subtitles, and the subtitle language to English.

Multimedia and embedding 3

For this final task you have two tasks to do:

  • Embed a PDF into the page. The PDF is called mypdf.pdf, and is contained in the media folder.
  • Go to a sharing site like YouTube or Google Maps, and embed a video or other media item into the page.

Assessment or further help

You can practice these examples in the Interactive Editors above.

If you would like your work assessed, or are stuck and want to ask for help:

  1. Put your work into an online shareable editor such as CodePen, jsFiddle, or Glitch. You can write the code yourself, or use the starting point files linked to in the above sections.
  2. Write a post asking for assessment and/or help at the MDN Discourse forum Learning category. Your post should include:
    • A descriptive title such as "Assessment wanted for HTML image basics 1 skill test".
    • Details of what you have already tried, and what you would like us to do, e.g. if you are stuck and need help, or want an assessment.
    • A link to the example you want assessed or need help with, in an online shareable editor (as mentioned in step 1 above). This is a good practice to get into โ€” it's very hard to help someone with a coding problem if you can't see their code.
    • A link to the actual task or assessment page, so we can find the question you want help with.
