What is CSS View Transition Generator?
The CSS View Transition Generator builds the view-transition-name declaration and the matching ::view-transition-old() and ::view-transition-new() pseudo-element rules you need to animate smooth morphs between two DOM states. You set the duration, timing function, mix-blend-mode and animation-direction, see a simulated live preview, and copy valid, paste-ready CSS for both same-document (SPA) and cross-document (MPA) transitions.
Key Benefits
- Generates the full set of view-transition pseudo-element rules in one click
- Duration, easing, blend mode and animation direction controls
- Live validation of the view-transition-name custom-ident
- Copy-ready, valid CSS that drops straight into any stylesheet
- 100% client-side - works offline and keeps your markup private
Common Use Cases
- •Animating a hero image morph between SPA route changes
- •Building shared-element transitions between list and detail views
- •Prototyping cross-fade durations before wiring up the API
- •Generating the CSS scaffold for cross-document (MPA) page transitions
How to Generate CSS View Transitions
- Enter a transition name: Type a view-transition-name such as hero-image. The field validates it is a valid CSS custom-ident (letters, numbers, hyphens).
- Set duration and easing: Choose an animation duration in milliseconds and a timing function (ease, ease-in-out, or a custom cubic-bezier).
- Tune blend and direction: Optionally set mix-blend-mode for cross-fade layering and animation-direction (both, reverse, alternate) for the group pseudo-element.
- Copy the CSS: Read the generated ::view-transition-old/new() rules and click Copy to paste them into your stylesheet or transition layer.
