Tooltip or Dropdown That Truncates Under Text-Spacing Overrides

1.4.12 — Text Spacing

Scenario

Setting

A recipe site's ingredient list

What’s wrong

Tooltips/dropdowns sized to unspaced text truncating under override.

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 open tooltips/dropdowns: if they're sized for unspaced text and now truncate, 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 recipe site's ingredient list, this barrier is gone for people with dyslexia or low vision who apply extra text spacing to read — they can complete the task without hitting this wall.
