Modern CSS Techniques Every Developer Should Know in 2026

CSS has evolved dramatically over the past few years. Features that once required JavaScript or complex workarounds are now possible with pure CSS. Let's explore the techniques that are defining modern web styling.

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 that work anywhere in your layout.
