If you are working in a team of designers and developers, it is useful to keep everyone up to date when something changes, such as the addition of a new corporate color, a change to a corporate color, a change to the size of button on the website or any other style change. The team library is the solution to this challenge.
How does Figma work? Styles and components live inside the files in which they were created. You will want to be able to re-use those across all your Figma files. You do this by publishing them to your team library. With the free starter team, you can publish your styles. To publish components, the file will need to belong to a project within a professional team or organization plan.
