Validating Vendor Prefixes in CSS: Unlocking the Secrets of -webkit- and -moz-

The use of vendor prefixes in CSS, such as -webkit- and -moz-, enhances cross-browser compatibility. However, these prefixes can hinder CSS validation. Is there a way to navigate this validation hurdle?

Unveiling the Validation Dilemma

The CSS3 Syntax module acknowledges the existence of vendor extensions but fails to recognize them as official CSS properties. This stance remains unchanged, as these extensions are proprietary and vendor-specific.

Introducing a Validation Enhancement

A recent upgrade to the Jigsaw W3C CSS Validator offers a solution to mitigate the validation challenges posed by vendor extensions. By expanding the "More Options" section, developers can find a new option that converts validation errors triggered by vendor extensions into warnings.

Unlocking the Benefits

This enhancement streamlines the process of identifying actual validation issues within a stylesheet. If vendor extensions are the sole cause of errors, converting them to warnings allows the stylesheet to tentatively pass validation. Additionally, developers no longer need to maintain vendor extensions in separate stylesheets that require hiding from the validator.

Embracing Validation Warnings

While converting errors to warnings provides a compromise, it's important to recognize that vendor prefixes remain non-standard and technically invalid CSS. Therefore, turning errors into warnings is the closest approximation to validation without sacrificing the benefits of cross-browser compatibility.
