My upcoming Oslo Elm Day talk, Audio & Video in Elm: Best Practices for Multimedia has lots of content, so I had to cut out a huge number of best practices.
I cut the ones that are most general–these are basically the way you should do it in either Elm or plain ol’ Html. However, for each I also included notes on how to each in Elm.
Most of these are follow browser-vendor guidelines. A few come from my personal experience.
EDIT: These were adapted from notes. My hope is to expand this in the near future with Ellie examples for each.
