Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
In Mozilla applications like Firefox, the -moz-outline-radius
CSS shorthand property can be used to give an element's outline
rounded corners.
/* One value */ -moz-outline-radius: 25px; /* Two values */ -moz-outline-radius: 25px 1em; /* Three values */ -moz-outline-radius: 25px 1em 12%; /* Four values */ -moz-outline-radius: 25px 1em 12% 4mm; /* Global values */ -moz-outline-radius: inherit; -moz-outline-radius: initial; -moz-outline-radius: unset;
