This test is validating all used CSS on the url specified. We are currently sending following sources to W3C CSS Validation for validation:
- Inline CSS in
style-element - Inline CSS in
style-attribute - CSS referenced using
link-element
Addition to test all of above sources (compared to only test inline styles that W3C CSS Validation do) we are also adding support for:
- Draft CSS properties by using MDN Web Docs - CSS reference as guidance.
100%as valid value offont-stretch- Draft CSS functions by using MDN Web Docs - CSS reference as guidance.
For every source (see above) we are calculating rating based on:
- Number of different error types
- Number of total number of errors
we are then combining the results.
Math used are:
rating_number_of_error_types = 5.0 - (number_of_error_types / 5.0)rating_number_of_errors = 5.0 - ((number_of_errors / 2.0) / 5.0)
As always, minimum rating are 1.0.
