A company you develop for wants to temporarily change the design for their main page for a company anniversary celebration. Because this will be a specific version of the main page that is published for a specific period, which Sitecore feature enables you to accomplish this change while easily allowing you to revert to the original design?
Versioned layouts in Sitecore allow you to create multiple versions of a page's layout, enabling you to implement temporary changes and easily revert back to the original design after the specified period. This is particularly useful for time-bound events or special occasions such as a company anniversary celebration.
Publish a specific version with its own layout for a specific period. https://doc.sitecore.com/xp/en/developers/102/sitecore-experience-manager/versioned-layouts.html
