Usage

This function runs automatically, so it is not called manually. Is this incorrect?

Demo

Large image loaded normally (not lazy-loaded).

This should appear in a Lighthouse audit under Performance > Opportunities > Offscreen images > View Details

Large image loaded using lazy-load.

Despite being very similar to the previous large image, it will not appear in the same Lighthouse audit.

Lazy loading a background image with the .lazy-load class

This should also not appear in the same Lighthouse audit as above.

Iframe loaded using `lazy_iframe()`.

Additional Notes

For <img> elements, you can use the lazy_img() function (or lazy_load()).
For <iframe> elements, you can use the lazy_iframe() function (or lazy_load()).
For all other HTML elements, use the lazy_load().
For background images, add the class .lazy-load to the element.

Warning: The HTML (<img>, <iframe>, etc.) methods support non-JavaScript environments, but the .lazy-load method requires JavaScript to work.

To trigger the load function manually, use nebula_load event trigger: jQuery(document).trigger('nebula_load');

Once the load function is triggered, the listeners are removed (except for the force_load trigger) as they are no longer needed.
