FAQPage Schema

How do I use the View Transition API for animated page transitions?▼

The View Transition API handles smooth animated UI transitions by utilizing the `startViewTransition` method. You can implement both same-document and cross-document transitions by applying specific JavaScript methods and associated CSS pseudo-elements.

What CSS properties and selectors are needed for view transitions?▼

View transitions require specific CSS pseudo-elements, properties, and at-rules to control the animation. The API provides dedicated CSS selectors that target the transition snapshots, allowing you to customize the visual effect during the document state change.

What is the difference between same-document and cross-document view transitions?▼

Same-document transitions animate state changes within a single page using the `startViewTransition` method. Cross-document transitions enable smooth animated navigations between separate URLs in a web application, utilizing the same underlying View Transition API mechanisms.

Can I use the View Transition API to debug broken UI animations?▼

Yes, you can debug broken UI animations by referencing the mirrored MDN content for View Transition API methods and interfaces. This local documentation helps identify incorrect syntax or missing CSS properties causing the animated transition to fail.

Does the View Transition API work without any external dependencies?▼

The View Transition API is a native web platform feature requiring no external dependencies to implement. You only need standard JavaScript and CSS to utilize the `startViewTransition` method and its associated pseudo-elements for animated transitions.
