Async CSS & JS

This plugin automatically adds async attributes to CSS and defer attributes to JavaScript for all enqueued assets on a site. It is designed for developers and site owners who want to improve page load performance without manually editing theme files or modifying each script and style registration.

Key features and benefits:

• Automatic tag insertion – Applies async to CSS and defer to JS across all enqueued assets with no per-file configuration required.
• Out-of-the-box operation – Works immediately on simple sites without additional setup or code changes.
• Browser fallback support – Uses the loadCSS library as a fallback for browsers that do not support the async attribute, ensuring consistent behavior.
• Performance improvement – Reduces render-blocking resources, allowing the page to display content faster while assets load asynchronously.
• Plugin compatibility awareness – Notes that plugins relying on inlined JavaScript (such as Gravity Forms) may require adjustments, helping developers anticipate and resolve conflicts.
