How do you keep design files and code aligned?
Agree on component names, adjustable options, states, and responsive behaviour across design and development.
Design and code need shared agreements that both roles understand. These describe names, permitted changes, state triggers, and how to check the result in a browser.
Keep these basics in mind
- Here, an interface means the options available when using a component, such as text, size, and loading state. It does not mean a backend data API.
- An interaction specification describes what happens after an action. Screenshots alone cannot fully explain errors, keyboard use, or narrow-window behaviour.
- Names and purposes need to correspond, though code syntax may differ. A primary action in the design should have an identifiable implementation.
- Acceptance checking compares implementation with the agreement. Check appearance and behaviour on the real page.
See Figma’s asset-description guide for cross-role explanations and USWDS code guidance for web semantics and implementation foundations.
A collaboration process
Illustrative agreements
These are teaching examples, not actual project interfaces.
| Item | With screenshots alone | With shared agreements |
|---|---|---|
| Button text | Copy the example | Editable and allowed to grow sensibly |
| Saving | Unspecified | Show processing and prevent duplicate submission |
| Narrow window | Wide drawing only | Explain when to stack areas |
Walk through an example
An invitation-form handoff covers fields, errors, button loading, and narrow-window layout. After implementation, both roles check a long email and failed submission. If error text differs from the design guidance, they clarify the rule before updating code and documentation.
Limits and common misunderstandings
Exported code snippets do not provide complete product behaviour. Validation, permissions, and network failure still require implementation. Similar pixels do not establish correct keyboard order, accessible names, or action results.
