Frequently Asked Questions

Common questions about Lazy Load Optimizer

Just activate the plugin. Additional settings is not required.

Lazy loading is the strategy of loading resources as they are needed, rather than in advance. This approach frees up resources during the initial page load and avoids loading assets that are never used. Images that are offscreen during the initial pageload are ideal candidates for this technique.

Add width and height attributes to image. <img width="200" height="100" src="image.jpg">

In case you want to lazyload a background image via a class you can do so by using the addClasses option: <style> .bg-stage.lazyloaded { background-image: url(lazyloaded-bg.jpg); } </style> <div class="bg-stage lazyload">  </div>
