Theme Changing Template • KhanDevs

Production-ready theme architecture

A reference Next.js implementation for theme switching. Uses CSS variables, class-based theming, and View Transitions to avoid flicker, hydration issues, and inconsistent UI states.

Under the hood

We use the View Transitions API to capture old/new UI snapshots, then reveal the new theme using a circular clip-path expanding from the toggle button.

1

Capture view

The browser snapshots the current UI before the theme updates.

2

Switch theme

next-themes updates the class + CSS variables for the new theme.

3

Reveal smoothly

A clip-path circle expands from the toggle button to cover the screen.
