developing Core requirement

Blocks Of Text Adjustable

Group: text-and-wording • Guideline: text-appearance

Summary in Plain English

The presentation of blocks of text can be adjusted without losing content or functionality - inline margin, block margin, line length, line height and justification. The exact values are still to be determined in the draft. Hard-coded styling, such as raw text that is already capitalised or hyphenated, is exempt.

Why It Matters

Readers with dyslexia, low vision or attention-related disabilities often need wider spacing or shorter lines. Layouts that break when those change force a choice between reading comfortably and reading at all.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/text-and-wording/text-appearance/blocks-of-text-adjustable.md.

Except when

the style attribute is hard-coded, such as raw text that is capitalized or hyphenated.

Notes in the draft

The requirement is that the text is manipulable and the style attributes can be overridden.
