Write CSS using the Tideway design system — fixed design tokens (colors, spacing, typography, breakpoints) and strict BEM class naming, in plain CSS with no framework. Use whenever writing or editing CSS in a project that uses Tideway, styling a new component or page, choosing colors/spacing/font sizes, or when the user mentions Tideway, design tokens, or BEM.
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
# Tideway: style Tideway is a design system delivered as a convention: fixed design tokens plus strict BEM, written as plain CSS. There is no build step, library, or runtime — consistency comes entirely from following these rules, so follow them exactly. ## Core rules 1. **Default every value to the scale.** Colors, spacing, font sizes, line heights, radii, shadows, and breakpoints are all defined in `references/tokens.md`. Read it before writing any CSS. When a design calls for something between two tokens, use the nearer one. This is a strong convention, not a ban: if a value is genuinely off-scale, use the raw value rather than distorting the design to force-fit a token — but do that deliberately, not by defaulting to arbitrary values out of habit. 2. **Reference tokens as custom properties — don't inline their values.** Declare the tokens you use in the project's `tokens.css` and write `padding: var(--space-4)`, not `padding: 1rem`. An inlined value satisfies the scale today but severs the link to the token, so it can't be found, audited, or re-themed later. …

How to install
mdr add matthewp/tideway/style@sha256:fc9b2047266a3585The line at the top of this page pins the label git:20260711.7e03b45, 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.
