CSS conventions, layout systems, and modern patterns: predictable styles through low specificity and explicit cascade control. Invoke whenever task involves any interaction with CSS code — writing, reviewing, refactoring, debugging, or understanding stylesheets, SCSS, layout, or responsive design.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CSS
**Predictability is the highest CSS virtue. If your styles require `!important` to work, restructure the cascade.**
CSS rewards explicit, low-specificity selectors and intentional cascade ordering. Prefer boring, readable patterns over
clever one-liners.

- **Layout** — [`${CLAUDE_SKILL_DIR}/references/layout.md`]: Flex shorthand values, grid details (subgrid, implicit
rows, alignment), layout patterns
- **Modern CSS** — [`${CLAUDE_SKILL_DIR}/references/modern-css.md`]: Extended modern CSS patterns and examples
- **SCSS** — [`${CLAUDE_SKILL_DIR}/references/scss.md`]: `@forward` patterns, module configuration, built-in modules,
file organization
- **Responsive** — [`${CLAUDE_SKILL_DIR}/references/responsive.md`]: Extended responsive design patterns and examples
- **Methodologies** — [`${CLAUDE_SKILL_DIR}/references/methodologies.md`]: Methodology patterns and architecture details
## Selectors and Specificity
- Single class selectors by default — keep specificity flat at 0-1-0
- Never use ID selectors for styling — IDs are for anchors and JS hooks
- Never qualify classes with elements — `.error` not `div.error`

How to install
mdr add xobotyi/cc-foundry/css@sha256:189e4cfc0f2d9afeThe line at the top of this page pins the label git:20261026.61ec950, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
