Validating W3.CSS
Validating W3.CSS might return some errors.
You will often get some errors when you run W3C validations.
There will always be some browser specific values outside the current W3C specification.
| Property | Description |
|---|---|
| pointer-events | Invalid property in CSS3, but suggested for CSS4. Used in W3.CSS to remove hand pointer from disabled elements. |
| user-select | Invalid property in CSS3, but suggested for CSS4. Used in W3.CSS to remove text selection from clickable elements. |
| pseudo-class :valid | Invalid value in CSS3, but suggested for CSS4. Used in W3.CSS to indicate valid input. |
| @-webkit-keyframes | Added to W3.CSS to make animations work in webkit browsers (older versions of Chrome, Safari, and Opera). |

W3.CSS is Normalized
Normalizing a style sheet is done to:
- Correct browser bugs
- Remove browser inconsistencies
- Assure common browser defaults
- Normalize the styles of all HTML elements
- Add CSS improvements
An extract fromNormalize.css is used in W3.CSS.
This makes W3.CSS display HTML consistently in all browsers, and in line with modern web standards.
