I tried to check my CSS using both validators and they give different results!
http://www.css-validator.org/ returns far more errors (245 in my case) than http://jigsaw.w3.org/css-validator/ (which returned 24 errors).
What is the difference between the two? Aren't they under W3C?
The options I used for http://jigsaw.w3.org/css-validator/ :
- Profile: CSS level 3
- Medium: all
- Warnings: all
- Supplier Extensions: Default
I also tried changing the value of the Vendor extension, if I set it to Errors, I get about 100 errors, if I set it for warnings, I get the same number of errors as the default, which is 24.
The options I used for http://www.css-validator.org/ :
- Profile: CSS level 3
- Medium: all
- Warnings: all
Examples of errors not returned by css-validator.org but not jigsaw.w3.org:
- ". kill-flicker: property reverse visibility property does not exist: hidden hidden
- ": Unknown pseudo-element or pseudo-class :: - moz-focus-inner [-moz-focus-inner]"
