Carousel uses bad value for perspective property
Created by: cvrebert
https://github.com/twbs/bootstrap/blob/2e6511bb51d23b1f54d2a2ed32282e4a50ba959a/less/carousel.less#L32 ends up compiling (in part) to perspective: 1000;
However, per the spec and https://developer.mozilla.org/en-US/docs/Web/CSS/perspective , perspective
's value must be either none
or a length. Non-0
lengths must have a unit, so the unitless 1000
is invalid.
