Site behaviorYou can refine certain site behaviors in the Site settings > Template > Advanced > Site behaviors tab. These behaviors are as follows:
Center active content
This will vertically center this content on the screen when a left or right arrow is clicked.
Preload pages on first load
This loads all text content on your site at once. This means the first page may take longer to load, but other pages should load much faster. This is not recommended for sites with many pages (more than 20) or many images (more than 100).
Reload images on resize
This attempts to load optimized image sizes based on the new browser window size. However, the images may flash briefly during this time.
Always display loaders for images
This will display a loading icon for every image, even in galleries that have many images on a page.
