Scroll-Driven Variable Fonts

Wire variable font axes directly to scroll position using animation-timeline — weight, width, and custom axes that respond to scroll with zero JavaScript.

Media Pseudo-Classes — :playing, :paused

CSS :playing, :paused, and :muted let you style media elements based on playback state — no JavaScript event listeners or manual class toggling needed.

ariaNotify()

ariaNotify() sends accessible announcements directly to screen readers — no live region markup, no invisible DOM nodes, no requestAnimationFrame timing hacks.

CSS revert-layer

revert-layer rolls a property back to its previous cascade layer value — the surgical undo that revert and unset can't provide when working with @layer.

light-dark() Image Support

The light-dark() function now accepts image values — swap photos, SVGs, and gradients between color schemes with a single CSS declaration.

sizes="auto" on Images

sizes="auto" lets the browser measure a lazy image's rendered width itself — no manual breakpoint math, no fragile sizes strings to maintain.

Element-Scoped View Transitions

element.startViewTransition() runs smooth snapshot crossfades on a single DOM subtree — list reorders, tab swaps, and card mutations without touching the rest of the page.

CSS border-image

border-image replaces standard borders with sliced images or gradients — the key to gradient borders, animated outlines, and decorative frames without extra DOM elements.

CSS border-shape

border-shape reshapes box geometry with a single keyword — squircles, superellipses, notches, scoops, and bevels in pure CSS without SVG or clip-path strings.

Multi-Column Wrap and Height Properties

column-wrap and column-height bring proper row-wrapping and height limits to CSS multi-column layout — magazine-style pagination without JavaScript.

Sticky Both Ways — X and Y Axis

position: sticky now works on the inline axis too — combine top and left offsets to freeze table headers, column labels, and UI chrome in two dimensions.

::search-text and :current Pseudo-Classes

Style find-in-page highlights with ::search-text and mark the active match with :current — replacing the browser's default yellow with your own design tokens.

CSS random()

The CSS random() function generates controlled randomness directly in stylesheets — per-element or shared, with optional step quantization.

Haptic Feedback API

The Vibration API delivers tactile feedback on mobile with a single method call — pulse patterns, drag feedback, and long-press cues without any native bridge.

Interop 2026

Style Queries Coming to Container Queries

Style queries let @container respond to CSS custom property values — not just dimensions — enabling token-driven component variants without JavaScript.

@scope CSS

@scope limits where CSS rules apply in the DOM — native scoping without build tools, Shadow DOM, or BEM class naming conventions.

Container Queries — Another Way to Scope CSS Natively

Named @container rules aren't just for responsive components — they're a practical CSS scoping boundary that requires no Shadow DOM or class namespacing.

Interop 2026

CSS Masonry — CSS Grid Lanes

Native CSS masonry via grid-template-rows: masonry lands in Interop 2026, replacing JavaScript layout engines with a single CSS property.

HTML in Canvas

Render styled HTML markup onto a canvas element today using SVG foreignObject, and get ready for the native drawHTMLElement() method coming to the Canvas 2D spec.

Pretext: Text Layout Without DOM Measurement

Pretext precomputes multilingual text measurement so you can ask for wrapped height and line ranges without touching the DOM or triggering layout reflow.
