I copied the standard 768, 1024, and 1440 breakpoints from a tutorial, and my layout still looks broken in between them.
What you'll have at the end
A short list of breakpoints, each one tied to a spot where your own layout actually breaks
You need
A row of a few peer items (stat cards, nav links, a filter bar) laid out with flexbox or grid, plus at least one media-query breakpoint copied from a tutorial or another project rather than tested against this row's own content.
Not covered
Reflowing an open-ended list of similar cards with no breakpoint at all, a separate technique for a list whose length keeps growing.
Build a responsive card grid with one CSS Grid line, no media queries
for an open-ended list of similar cards rather than a small fixed set, a grid that reflows on its own is usually the better fit, with no breakpoint to measure at all.
Replace a media-query font ladder with clamp()
if the only thing breaking is text size climbing in steps, a fluid clamp() fix removes the need for a breakpoint entirely.
