Simplify

    • adjusting line spacing and text size overrides this
Option 1: Responsive layout slider

  • move slider to decrease page width and activate responsive layouts where available
    • layout becomes linearized and prioritizes, negative space increases

Option 2: Article-only with table of contents

  • view only page article
  • navigate through the website using the TOC and search:
    • hierarchical links to all pages of the website
    • anchors to the headers of only the current page
  • No labels
