How CSS Resolves Multiple Matching Breakpoints
When multiple breakpoints match the current viewport size, CSS applies all matching rules, following the normal cascade and specificity rules. The later rule in the stylesheet (or one with higher specificity) takes precedence if there are conflicting declarations.
All matching media queries are applied simultaneously.
If multiple breakpoints define the same property, the last one in the stylesheet takes precedence.
Specificity and source order still apply — inline styles and !important rules override others.
Using a consistent order (e.g., smallest to largest) helps maintain predictable behavior.
