Responsive design is more than shrinking a desktop screen. Content should reflow naturally across widths and interaction methods.
Fluid containers
Limit long lines of text using max-width, flexible gutters and auto margins. Use responsive grid patterns rather than fixed pixel columns.
Typography that adapts
Choose font sizes and line lengths that remain readable on small devices. clamp() is useful for headings that need a smooth progression.
Validate real breakpoints
Test long labels, zoom, landscape orientation and touch targets. Breakpoints should reflect content behavior rather than only device marketing categories.
