1.4 Wednesday - classroom activities

1.5 Homework 6

Create an HTML5 file that includes at least

  1. a video in two different container variants (webm, ogg, mp4)
  2. an audio (mp3)
  3. and at least one VTT captions file for the video.
  • The page should be "meaningful" and usable with respect to a target population of your choice. (I.e. do not create a page for the instructor, identify an objective and a target population and implement for these ...)
  • You may copy/paste text and use media files from some other sources under the condition that you cite these sources.
  • You may keep the HTML very simple (i.e. only use h1, div and p tags), but you should try to produce a good user experience. (usability, usefulness and graphic appeal)
  • Submit the files to the worldclass room. Make sure to include the media files unless you link to accessible URLs. (We suggest using a zip file).
  • You may not submit the screencast for the term project as project 6
  • Due: Monday, week 8, before class
