Modern CSS Techniques You Should Be Using

By • min read

CSS Grid and Flexbox

CSS Grid and Flexbox have revolutionized web layouts. Grid excels at two-dimensional layouts while Flexbox handles one-dimensional alignment. Together, they eliminate the need for float-based layouts.

CSS Custom Properties

CSS variables (custom properties) enable dynamic theming and reduce repetition. They cascade like regular properties and can be modified with JavaScript for runtime theme switching.

Container Queries

Container queries allow components to adapt based on their container size rather than the viewport. This is a game-changer for component-based architectures and design systems.

CSS Animations

The View Transitions API and CSS scroll-driven animations bring native-feeling transitions to web apps. Combined with @keyframes and transition properties, you can create smooth, performant animations.

Modern Selectors

Selectors like :has(), :is(), and :where() provide powerful targeting capabilities. The :has() selector, often called the "parent selector," enables styling based on child elements.
