Lazy Loading Page
Normally when a user opens a webpage, the entire page’s contents are downloaded and rendered in a single go. While this allows the browser to cache the web page, there’s no guarantee that the user will actually view all of the downloaded content.
Instead of bulk loading all of the content when the page is accessed, content can be loaded when the user accesses a part of the page that requires it. With lazy loading, pages are created with placeholder content which is only replaced with actual content when the user needs it.

When enabled Lazy load can help to improve the loading speed of a media rich web page.
The miscellaneous settings give you access to a range of other features you may wish to integrate into your site.
Disable Mobile Animation
This option lets you disable animation on the SM and XS breakpoints.
Pre-Loader Settings
To improve the presentation of your website, Blocs automatically integrates a small preloading animation. This animation is displayed in the visitor’s browser until the site is fully loaded. Once your site is fully loaded, the pre-loader will automatically disappear and the webpage will be shown.
