Switching to a mobile layout before the viewport truly needs it wastes space and harms usability; add intermediate breakpoints or use container queries to keep designs fluid.
Too early breakpoints force a full switch to a mobile layout the moment the viewport shrinks a little, leaving a lot of unused space and a jarring user experience. The article shows that this is not a clever shortcut but a symptom of missing intermediate design states.
Real-world examples from Time.com and TechCrunch illustrate the problem: their hero sections jump to a full-width mobile layout at a width where a desktop layout could still work nicely. The author even includes demo videos where the layout only changes after the video finishes, highlighting how premature breakpoints break the flow.
Technical leaders should care because developers and designers regularly resize browsers, use split-screen view, or view sites on tablets and iOS link previews. In each case the premature breakpoint makes the UI look broken, wasting developer time fixing edge cases and confusing users.
The fix is straightforward: discuss with designers to add more breakpoints, design with container queries, and build layouts that adapt based on content size. Modern CSS tools like Grid, Flex, and container queries let you keep the design fluid without hard-coded early switches.
The piece also points to a larger CSS course, The Layout Maestro, where the author expands on these techniques and shows how to rebuild problematic layouts from scratch.
