Breakpoint

A breakpoint is a specific threshold value, usually expressed in pixels, at which the layout of a website or application changes to adapt to the screen size. Technically, developers use CSS media queries to define these switching points. Breakpoints allow interface elements to be reorganized (for example, moving from three columns to a single column) in order to ensure an optimal user experience across all devices, from smartphones to ultra-wide screens. Rather than relying on standard device sizes (iPhone, iPad, etc.), best practice today is to define breakpoints where the content itself starts to visually break or lose clarity.
