-webkit-text-stroke

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.

The -webkit-text-stroke CSS property specifies the width and color of strokes for text characters. This is a shorthand property for the longhand properties -webkit-text-stroke-width and -webkit-text-stroke-color.

Initial value	as each of the properties of the shorthand: `-webkit-text-stroke-width`: `0` `-webkit-text-stroke-color`: `currentcolor`
Applies to	all elements
Inherited	yes
Media	visual
Computed value	as each of the properties of the shorthand: `-webkit-text-stroke-width`: absolute `width` `-webkit-text-stroke-color`: If the value is translucent, the computed value will be the `rgba()` corresponding one. If it isn't, it will be the `rgb()` corresponding one. The `transparent` keyword maps to `rgba(0,0,0,0)`.
Animation type	as each of the properties of the shorthand: `-webkit-text-stroke-width`: discrete `-webkit-text-stroke-color`: a color
