This PR applies some editorial fixes in-line with the W3C Manual of Style:
W3C Manual of Style preferred terms:
- style sheet over stylesheet (it has a space in CSS)
- white space over whitespace
- variables to factors (variables conflicts with CSS)
- The W3C to W3C (Sans is preferred).
- they/them over he/she/him/her (etc).
- Added some more abbreviations.
- Removes "normative" mentions as per (glance.html: editorial: replace "normative" tech spec w "full document" #120).
I've also applied hotfixes where prior bugs have occured and drawn all the docs in-line with pubRules:
- All div/sections now have an associated ID.
- QuickRef header now links to the PDF alternative.
- All documents now have a required SoTD template.
- Increased luminosity of click regions (WCAG friendly).
- Added dark mode to all documents via ReSpec.
I've applied a couple of editorial tweaks to two SC's based on discussion with Rose to align with W3C QA spec.
I also fixed some improper use of double spacing, case usage, and non-standard characters.
