scroll-snap
This can Implementing native scrolling and deceleration
@media(prefers-*)
Helps tailor the UI and UX of the page based on the user’s device preferences, allowing for a higher level of personalization.
* Can represent brightness, force color, color scheme, contrast, reduce motion, and reduce transparency
Position: Stickiness
to keep the UI within the viewport.
Logical properties with standard layout
Allows us to have dynamic directional spacing inside and around elements.
gap property
This property is now available for Flexbox. Gap sets the container to have spacing, rather than giving each child element its own spacing.
backfrop-filter

Layout API, Paint API, Parser API, Properties & Values API, AnimationWorklet, Typed OM and Font Metrics API fall under this scope.

CSS Subgrid
Helps us create microlayouts using microlayout in CSS grid.
