VS Code Extension for Baseline CSS/HTML Linting
CodeBaseline is a Visual Studio Code extension that checks your CSS and HTML code against web feature baselines. It highlights features that may not be widely supported across browsers, helping developers write future-proof, compatible code.
Inspired by modern web development challenges, this extension allows you to quickly spot potentially unsupported CSS properties or HTML elements, ensuring a smooth experience for all users.
Features:
- Real-time diagnostics for CSS and HTML
- Highlights features not included in the baseline
- Works on file save or live as you type
- Stores a local baseline cache (
baseline.json) for offline usage
- Download the latest
.vsixrelease from the Releases page. - In VS Code, go to the Extensions view →
...→ Install from VSIX.
