## What it does

The skill covers quote marks, dashes, ellipses and spacing in on-screen text. The agent applies the rules on its own whenever it writes markup or components, without asking first. A second mode handles audits: reviewing existing code, it flags violations and offers fixes.

Two reference files ship with it: `references/css-templates.md` with a CSS baseline and OpenType settings, and `references/html-entities.md` with the entity table. The rules are distilled from Matthew Butterick's Practical Typography. There is a warning about JSX: escape sequences such as `\u2019` inside text between tags render literally, so you need either the real UTF-8 character or an expression in curly braces.

The skill targets any code with visible text: landing pages, dashboards, presentations, documents. If your project already runs a typography linter, the skill will duplicate its warnings, so it is worth deciding which one wins.

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/bencium/bencium-marketplace/tree/HEAD/typography/skills/typography/SKILL.md

## When to use it
- get curly quotes and proper dashes into interface copy
- find typography violations in legacy code and get fixes
- set up a CSS baseline with OpenType features
- fix apostrophes in JSX that render as escape sequences
- unify spacing around punctuation marks

## Example prompts
- build a landing page for the new product, apply the typography rules yourself
- check the typography in this component and show me what to fix
- create a dashboard with an orders table, format the text by the rules

  Professional typography rules for UI design, web applications, software interfaces, and all screen-based
  text. Enforces timeless typographic correctness that LLMs consistently get wrong: proper quote marks,
  dashes, spacing, hierarchy, and layout. ENFORCEMENT MODE: When generating ANY HTML, CSS, React, JSX,
  or UI code containing visible text, auto-apply every rule in this skill silently — do not ask, do not
  explain, just produce correct typography. AUDIT MODE: When reviewing or improving existing interfaces or
  legacy code, flag violations and provide fixes. Trigger on: any HTML/CSS/React artifact creation, "build
  a landing page", "create a component", "design a UI", "fix the typography", "make this look professional",
  "review this layout", web design, presentation design, dashboard creation, document generation, or any
  task producing visible text for humans. Even if the user doesn't mention typography, apply these rules
  whenever generating UI output.

# UI Typography Skill

## Attribution

These rules are distilled from **Matthew Butterick's *Practical Typography*** (https://practicaltypography.com).
Butterick is a typographer, writer, and type designer whose work bridges professional typography and everyday
digital writing. Thank you, Matthew, for making this knowledge accessible and encyclopedic. If you find this
skill valuable, consider supporting his work directly.

## Mode of Operation

These are **permanent rules** — not trends, not opinions. They come from centuries of typographic practice,
validated by how the human eye reads. They do not go out of style.

**ENFORCEMENT (default):** When generating ANY UI with visible text, apply every rule automatically. Use
correct HTML entities, proper CSS. Do not ask permission. Do not explain. Just produce correct typography.

**AUDIT:** When reviewing existing code or design, identify violations and provide before/after fixes.

**Reference files** (read when generating CSS or looking up entities):
- `references/css-templates.md` — Full CSS baseline template, responsive patterns, OpenType features
- `references/html-entities.md` — Complete entity table with all characters and codes

## Characters

### Quotes and Apostrophes — Always Curly

Straight quotes are typewriter artifacts. Use `“` `”` for double, `‘` `’` for single.

Apostrophes always point down — identical to closing single quote `’`. Smart-quote engines wrongly
insert opening quotes before decade abbreviations ('70s) and word-initial contractions ('n'). Fix with
explicit `’`.

The `<q>` tag auto-applies curly quotes when `<html lang="en">` is set.
