A Framer feature that automatically arranges child elements in a row or column with consistent spacing, similar to CSS Flexbox. This powerful tool creates responsive designs that adapt to content changes—add or remove items and the layout adjusts automatically. Auto Layout is essential for building reusable components like navigation bars, card grids, and form fields.

A specific screen width where your design adapts to a different layout, ensuring your site looks good on all devices from phones to large monitors. Strategic breakpoint choices prevent awkward in-between states where content becomes cramped or overly stretched. Framer's breakpoint system lets you customize layouts at each size while maintaining a single source of truth for your design.

Rules that define how an element should resize or reposition when its parent container changes size. Constraints control whether elements stretch, stay fixed, or maintain proportional relationships during responsive resizing. Setting constraints correctly in Framer ensures your layouts adapt elegantly across different screen sizes.

A layout system that divides space into rows and columns, creating alignment and structure for content placement. Grid systems ensure visual consistency and make responsive design more predictable. Framer supports CSS Grid concepts through layout tools that adapt columns and gaps across breakpoints.

CSS rules that apply different styles based on device characteristics like screen width, orientation, or resolution. Media queries enable responsive design by adapting layouts at defined breakpoints. Framer handles media queries automatically based on your breakpoint configurations.

A design approach that starts with the mobile experience and progressively enhances for larger screens. Mobile-first forces prioritization and ensures the smallest screens get the best experience, not a squeezed afterthought. This approach often results in cleaner, more focused designs at all screen sizes.
