Do anyone know why all default values for text-overflow work in google Chrome except from the "string" value?
if you want to check it you can open mozilla and chrome with this link: https://css-tricks.com/almanac/properties/t/text-overflow/
then you can go to the first "codepen" box which shows the implementation and inspect the performance when text-overflow: "---" in both browsers.
In mozilla firefox 45.0 works, but in chrome 49.0.2623.87 (64-bit) doesn't.. and the error is invalid property value...
Simply, it is not supported by Chrome.
