CSS border less than 1px

Question

Border:1px is too large by default. Border: 0.5px solid; is not functioning, though. Is there a CSS trick that would reduce the border's size in half?

Answer 1

The minimum width that your screen can display is 1 pixel. So its impossible to display less then 1px. 1 pixels can only have 1 color and cannot be split up.

A CSS pixel isn't necessarily the same as a hardware pixel, and the gap is widening with higher and higher display densities.
