INSIGHT

Scoped Registries Reduce Name Pollution

  • Scoped custom element registries let multiple registries coexist so identical tag names can be reused in different scopes.
  • This reduces the need for awkward namespacing or long prefixed custom element names.
INSIGHT

Scroll-Driven Animations Go Declarative

  • Scroll-driven animations enable rich visual effects tied to scroll progress beyond simple reveal animations.
  • When interoperable, these will let authors declaratively drive complex animations directly in CSS.
ADVICE

Test ScrollSnap Across Browsers

  • Use ScrollSnap carefully and test across browsers because small inconsistencies affect UX, especially with nested or re-layout scenarios.
  • Check web-platform-tests to find and guard against subtle snapping behavior differences per browser.
