Assessment requested for accessibility troubleshooting one

Hello!

Here is the link for the question I attempted:

Here is the link for the code:
https://jsfiddle.net/fgzw783e/

What I have done
I went through this simple web page with NVDA and found that the following are now accessible to it:

  • headings
  • table
  • images (alt text added)
  • play and pause buttons for audio clip
  • comment button
  • all text fields

Additionally, I have added a transcription for the audio clip below.

This may be fore a school assignment, however I would still love feedback to improve my skills in coding accessible websites!

Thank you.
