How do I pre-load critical assets?

Preloading of critical assets is a premium feature of WP-Optimize.

Some assets which are considered critical might be loaded later because they are included via a script or from within a CSS file.

Typical examples include font files and background images. Loading these types of assets i.e. ones that users need for a page to function correctly, after non-critical assets doesn’t make sense. It negatively impacts page load times and user experience.

Preloading those assets however enables them to be loaded in priority order.
