Module ring_width 

Utilities for creating outline rings with box-shadows.

Class	Properties
ring-<integer>	box-shadow: 0 0 0 calc(<integer>px + var(--en-ring-offset-width)) var(--en-ring-color);
inset-ring-<integer>	box-shadow: inset 0 0 0 calc(<integer>px + var(--en-ring-offset-width)) var(--en-ring-color);

Tailwind compatibility

Ring width values don’t follow Tailwind’s philosophy of limiting possible values and all numbers are supported. They are however perfectly compatible with Tailwind’s values.

Arbitrary values

Any <length> property is allowed as arbitrary value. For example, ring-[1.2rem].
