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 from Normalize.css is used in W3.CSS.

This makes W3.CSS display HTML consistently in all browsers, and in line with modern web standards.

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.
