Design systems for marketing websites: scale without chaos

A design system is shared vocabulary: colors, type scales, spacing, and reusable UI patterns documented where designers and developers can both reach them. For marketing sites, the payoff is faster campaign landing pages, fewer one-off CSS hacks, and accessibility that improves everywhere when you fix a component once.

Start with tokens, not pixel pushing

Define semantic tokens (primary text, surface, border) rather than hard-coding hex values in every block. When brand refreshes, you update tokens and roll the change systematically. Pair tokens with a sensible type scale so headings stay hierarchical on mobile and desktop without manual tweaks.

Component boundaries

• Hero, feature grid, testimonial strip, pricing table, FAQ accordion.
• Form primitives: labels, errors, helper text, consent checkboxes.
• Media wrappers that enforce aspect ratio and lazy loading.

Governance without bureaucracy

Someone needs to approve new patterns—or you accumulate drift. A lightweight RFC in a shared doc, a monthly UI review, and Storybook (or equivalent) for QA beats a heavy committee. Document when to fork a component vs compose existing ones.

Systems age; schedule periodic pruning of unused variants. Dead components confuse new hires and slow builds.
