What does text-expansion do?

It helps your agent check that CSS for fixed-size or truncated elements has room for longer translated text.

Does text-expansion support all CSS properties?

It focuses on fixed dimensions, truncation, and overflow rules. Other CSS properties are not covered.

Can text-expansion automatically fix CSS?

No, it reviews and flags potential issues. You still need to make the changes.

What do I need to use text-expansion?

You need the CSS files and the translatable strings, plus the skill added to your agent's configuration.

Design UI components to accommodate text expansion from translation

SkillMedia

text-expansion is a skill that helps an AI agent review CSS for fixed dimensions, truncation, or overflow rules on elements that render translatable strings. It checks that fixed-size or truncated elements have room for longer translated text. This helps catch layout problems before translation breaks the interface.

What your AI can do with it

Review CSS for fixed dimensions on translatable elements
Check truncation and overflow rules for translated text
Flag elements that may not fit longer translations
Suggest adjustments to avoid text clipping

Getting started

Have the CSS files and the translatable strings available.
Add the skill to your agent's configuration.
Ask the agent to review the CSS for fixed dimensions, truncation, or overflow rules on elements that render translatable strings.
Review the agent's findings and adjust the CSS as needed.

What this skill tells your AI

The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/text-expansion/SKILL.md and read by ahel’s review.

Layouts designed only with English copy routinely break when translated: buttons overflow their containers, labels truncate, and navigation items wrap unexpectedly. Catching these issues early with pseudo-locale testing is far cheaper than fixing them after translations are delivered.

Quick Reference

German translations are typically 30% longer than English; Finnish 50% longer
Avoid fixed-width containers for text-bearing elements like buttons and labels
Use min-inline-size instead of inline-size to allow natural growth
Test with a pseudo-locale that inflates strings before committing translations
Include pseudolocalization in CI or preview testing, not just manual QA

Check

Identify CSS rules and component styles that use fixed widths or hard truncation on elements containing translatable text, which would break when content expands in other languages. Check that the team can test a pseudolocalized build or preview.

Fix

Replace fixed inline-size with min-inline-size on text containers, remove overflow: hidden from interactive elements, and add a pseudo-locale build step for visual testing in local development and CI.

Explain

Explain how text expansion during translation breaks fixed layouts and what CSS patterns prevent overflow and clipping across locales.

Code Review

Review CSS files and component styles for fixed widths, overflow: hidden, white-space: nowrap, and text-overflow: ellipsis on buttons, labels, navigation items, and headings that contain translatable text.
