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

-webkit-text-stroke: 4px navy; 
text-stroke: 4px navy;
/* Global values */
-webkit-text-stroke: inherit;
-webkit-text-stroke: initial;
-webkit-text-stroke: unset;
text-stroke: inherit; 
text-stroke: initial; 
text-stroke: unset;
