Text Overlapping the Section Below After Spacing Changes

1.4.12 — Text Spacing

Scenario

Setting

A fitness app's workout tracker

What’s wrong

Text overlapping following sections because ancestors use fixed heights.

Example

* { line-height: 1 !important; letter-spacing: 0 !important; }

Why it matters

People with dyslexia or low vision who apply extra text spacing to read.

How to test

Apply the text-spacing override and scroll: if enlarged spacing pushes text into the section below (fixed-height ancestors), causing overlap, it fails.

How to fix

With user text-spacing overrides applied (line height 1.5, paragraph 2x, letter 0.12em, word 0.16em), all content and controls must remain visible and usable. /* No !important overrides — let user style sheets adjust spacing */ !important locks out user stylesheets that increase line/letter/word spacing for readability.

Outcome

On a fitness app's workout tracker, this barrier is gone for people with dyslexia or low vision who apply extra text spacing to read — they no longer have to work around this.
