CSSStyleDeclaration.getPropertyCSSValue() and related interfaces have been removed

Published: | Categories: CSS, DOM


The support for the obsolete getPropertyCSSValue method on the CSSStyleDeclaration interface, deprecated in Firefox 61, has been removed with Firefox 62. The standard getPropertyValue method should be used instead. Given that Google Chrome has already removed the support back in 2014, the compatibility risk should be very low at this time.

Update: The following related interfaces have also been removed: CSSPrimitiveValue, CSSValue, CSSValueList, Rect and RGBColor.
