Understanding Device-Based vs Content-Based Breakpoints
Breakpoints in responsive design can be determined either by the dimensions of common devices (device-based) or by the layout’s natural breaking points (content-based). The key difference lies in what triggers the breakpoint — fixed device sizes versus flexible content needs.
Device-based breakpoints are chosen based on specific screen sizes of popular devices (e.g., 320px for phones, 768px for tablets, 1024px for desktops).
Content-based breakpoints are chosen where the design or layout starts to break or look cramped, regardless of the device size.
Device-based breakpoints can become outdated as new devices emerge with varying screen sizes.
Content-based breakpoints provide greater flexibility and maintainability by responding to the actual needs of the design rather than fixed device dimensions.
In this example, the breakpoints are not tied to specific device widths but are defined at points where the layout benefits from additional columns. This ensures the design adapts fluidly across any screen size.
