How does the View Transitions API create smooth page navigation animations?
❓ Interview Prompt: Explain the View Transitions API for cross-page morphing effects in SPAs and MPAs.
The View Transitions API enables smooth, animated transitions between page states or navigations:
How It Works:
1
Browser captures a screenshot of the current state.
2
DOM updates to the new state.
3
Browser captures the new state.
4
CSS animations morph between the two screenshots.
CSS Pseudo-elements:
•
::view-transition-old(root) — the departing page screenshot.•
::view-transition-new(root) — the incoming page screenshot.•
view-transition-name — marks specific elements for individual morphing.Code Implementation Example
css
/* Enable view transitions */
@view-transition {
navigation: auto;
}
/* Custom animation for page transitions */
::view-transition-old(root) {
animation: fade-out 0.3s ease;
}
::view-transition-new(root) {
animation: fade-in 0.3s ease;
}
/* Named element morph (e.g., hero image) */
.hero-image {
view-transition-name: hero;
}💡Cross-page view transitions with named element morphing.
🎯 Interview Key Takeaway
View Transitions API enables native page transition animations without JavaScript animation libraries.
