Is it wise to use fractional / decimal pixels for borders in css?
You can use it, but most browsers will round pixel value.

EDIT: Remember that one CSS pixel is not always equal to one physical screen pixel: A pixel is not a pixel is not a pixel

someoneHere about 2 years
I have various instances in my design that call for
border-right: 1.5px solid black; border-bottom: 1.5px solid black;
etc...
I also have design that needs thinner lines: at
1px
.However, it seems the browser may round the decimal, as I'm not seeing much differentiation between the two (if any).
Should I just be using
2px
and1px
instead, or is there a better way to pull this off?A designer I'm helping is very adamant about the
1.5px
line width.Any help, much appreciated.

zucker over 8 years@someoneHere Yes, you can use decimal value with percent, pt, em. But sometimes it can works inconsistently for different browsers.
