CSS Specifications
- The
lighting-color
property is defined in Filter Effects Module Level 1 (W3C Working Draft, 18 December 2018). - It is also defined in Scalable Vector Graphics (SVG) 1.1 (Second Edition) (W3C Recommendation 16 August 2011).
Vendor Prefixes
For maximum browser compatibility many web developers add browser-specific properties by using extensions such as -webkit-
for Safari, Google Chrome, and Opera (newer versions), -ms-
for Internet Explorer, -moz-
for Firefox, -o-
for older versions of Opera etc. As with any CSS property, if a browser doesn't support a proprietary extension, it will simply ignore it.
This practice is not recommended by the W3C, however in many cases, the only way you can test a property is to include the CSS extension that is compatible with your browser.
The major browser manufacturers generally strive to adhere to the W3C specifications, and when they support a non-prefixed property, they typically remove the prefixed version. Also, W3C advises vendors to remove their prefixes for properties that reach Candidate Recommendation status.
Many developers use Autoprefixer, which is a postprocessor for CSS. Autoprefixer automatically adds vendor prefixes to your CSS so that you don't need to. It also removes old, unnecessary prefixes from your CSS.
You can also use Autoprefixer with preprocessors such as Less and Sass.
