Modern CSS Techniques for 2026

CSS has evolved dramatically over the past few years. Features that once required JavaScript are now possible with pure CSS.

Container Queries

Container queries allow components to adapt based on their parent container's size rather than the viewport. This enables truly modular, reusable components.

Cascade Layers

The @layer rule gives you explicit control over the cascade. Organize your styles into logical layers and never fight with !important again.

Scroll-Driven Animations

Create stunning scroll-based animations without a single line of JavaScript. CSS scroll-driven animations are performant, accessible, and remarkably expressive.

@keyframes fade-in {
  from { opacity: 0; transform: translateY(20px); }
  to { opacity: 1; transform: translateY(0); }
}

.animation {
  animation: fade-in linear both;
  animation-timeline: view();
}

View Transitions API

The View Transitions API enables smooth animated transitions between page states, creating app-like experiences.
