Building Responsive Layouts Correctly (Intrinsic First, Media Queries Second)
Reach for flex, grid, minmax, auto-fit, and content-driven sizing before you add breakpoint files the project cannot maintain.
Intrinsic layout toolkit
CSS Grid and Flexbox can express most marketing and dashboard layouts without absolute widths. Start with content-based minima, then add gap using REM tokens.
When you do need pixel-perfect alignment to a hero image, translate measurements with PX to VW for fluid headers.
Breakpoint discipline
Breakpoints should track actual layout failure points, not device SKUs. Document them in a single module and generate snippets with the breakpoint calculator.
If you only adjust font sizes, try clamp() first—you may delete entire media blocks.
Frequently asked questions
- How many columns should a marketing grid have?
- Let min track width decide: `repeat(auto-fit, minmax(240px, 1fr))` adapts without custom counts per device.
