The border-top-radius
, border-right-radius
, border-bottom-radius
and border-left-radius
mixins are sometime used with subtracted variables, e.g.
.panel-heading {
.border-top-radius((@panel-border-radius - 1));
this can easily result in passing negative values (resulting in invalid border-radius values), e.g. bootswatch's Yeti theme.
I think it's better to protect against it.
