1.4.8 Visual Presentation (Level AAA)
What it requires: A bundle of text-block presentation options users can control: custom foreground/background colors, line width under 80 characters, no full justification, adequate line/paragraph spacing, and 200% resize without horizontal scrolling.
Common failure: Long-form blog content is fully justified (flush on both margins) with no user control over spacing or line length, creating uneven word gaps that are hard for some readers to track.
Fix it: Avoid full text justification by default, cap content column width, and provide adequate default line spacing — full user-controllable theming is a heavier lift usually reserved for content platforms, not typical e-commerce pages.
