How Does CSS Handle Overlapping Media Queries and Fractional Pixel Values?

Resolving CSS Media Query Overlap

Media Query Cascade

When multiple media queries match simultaneously, they behave according to the CSS cascade. All matching rules are applied, and their styles are merged based on specificity, inheritance, and the "!important" declaration.

Handling Overlap

To prevent overlap, media queries should be mutually exclusive. This can be achieved by using the "min-" and "max-"prefixes correctly. Inclusive ranges ensure that endpoints will match the relevant media query.

Fractional Pixel Values

In CSS, pixel values are logical pixels. It is unclear how browsers handle fractional pixel values in media queries. Some browsers may round to the nearest integer, ensuring that media queries with endpoint differences of less than one pixel will still match at those endpoints.
