Responsive Website Layouts
Plan responsive behaviour for grids, media, forms and navigation across phones, tablets and desktops.
Responsive means intentional adaptation
A responsive page should change layout where the content benefits, not simply scale everything proportionally. Two-column sections may stack, cards may reduce columns, navigation may become expandable and comparison layouts may use a different mobile representation.
The goal is to preserve hierarchy and task completion across screen sizes.
Test content extremes
Long headings, longer city names, validation messages, large prices and multiple navigation items often reveal layout weaknesses that clean mockup text hides. Test realistic content rather than only perfect design-system samples.
Images need responsive rules too
Different crops may be necessary for hero, card and mobile placements. Avoid hiding huge desktop images with CSS after they have already been downloaded.
Use stable containers
Reserve image space with width/height or aspect-ratio so loading does not push content around. Stable layouts improve both perceived quality and Core Web Vitals.
