Modern CSS Techniques Every Developer Should Know

CSS has evolved dramatically. Here are the modern techniques that have fundamentally changed how I approach styling.

Container Queries

Finally! We can style components based on their container size, not just the viewport. This is a game-changer for truly reusable components.

Cascade Layers

Using `@layer` brings sanity to specificity management. No more fighting with overrides.

Subgrid

CSS Subgrid lets nested elements align to their grandparent's grid — incredibly useful for card layouts.

:has() Selector

The parent selector we've been waiting for. `:has()` unlocks patterns that previously required JavaScript.

Conclusion

Modern CSS is incredibly powerful. These techniques reduce our dependency on JavaScript and make our styles more maintainable.
