An extension for Visual Studio Code that validates CSS according to W3C specifications and browser implementations.

This extension highlights incorrect at-rules, properties, and values in your CSS files. It utilizes the CSSTree capabilities to analyze CSS syntax and report any issues.

Note: If you encounter false positives or false negatives—such as unknown properties being flagged or invalid values not being detected—please report these issues on the CSSTree issue tracker.

Note: Currently, CSSTree does not support selector syntax matching. As a result, this extension does not validate selectors. Selector validation will be added once it becomes available in CSSTree (see issue #34).

Extension Settings

• csstree.enable: Enable or disable the CSSTree validator extension.

Troubleshooting

To prevent overlapping warnings with VSCode's default CSS linting, you can disable the built-in linter by adding the following setting to your configuration:

"css.validate": false
