[Shawn Lawton Henry]

published version: https://www.w3.org/WAI/fundamentals/foundations-course/

update 8 Dec:

• draft preview with TOC: https://deploy-preview-18--wai-fundamentals-overview.netlify.app/fundamentals/foundations-course/#course-comments-and-survey-response added TOC to published page
• Note that the TOC box also houses a callout box now -- so it looks better!

pro: people can more easily jump to the information they are more interested in. people will want different information first. Some will want to know who the course is for, others Duration, others Video excerpts from the course, and others maybe Course comments and survey responses.
