accessibility topic and additional content

[mandyWW]

Hi Bernard,

Just FYI I have modified the Day 1 Week 4 content as follows:

• Included a lesson on Web Accessibility where the students need to run Lighthouse & SiteImprove on their restaurant app / run it through a screen reader and fix the issues
• Added a fun assignment relating to events, creating their own Spooky Story based on a site I found earlier https://codepen.io/prosetech/pen/oRxMmZ
• Added an assignment to include Facebook like/share buttons to illustrate importing a js file and creating a counter to illustrate inline JS
• Added a PlantUML diagram to illustrate the DOM

Probably way to much content for Day 1 but I can move the AppRun stuff to the next day.

Feedback welcome although I will merge it in ready for the lesson but wanted you to have visibility.
