Lazy Rendering
What it does
Lazy Rendering delays painting Divi sections that are far below the fold (content-visibility) so long pages feel faster on first load. It is opt-in and is included in the Aggressive performance preset.
This is different from Smart Image Loading (images) and Background Images (backgrounds). The Visual Builder and previews are never affected. When Page Cache is on, Nitro can remember below-the-fold sections for a better first paint on cache HITs.

Settings
| Setting | Type | Default | What it does |
|---|---|---|---|
| Lazy Rendering | Toggle | Off | Delay painting far-below-the-fold Divi sections |
| Distance below the fold (pixels) | Number | 1800 | Only stamp sections whose top is at least this far below the viewport top. Higher values mark fewer sections |
| Exclude selectors | Text | empty | One CSS selector per line. Matching sections (or sections inside a match) are never lazy-rendered — useful for sticky CTAs or mega menus |
When to use it
- Long landing pages with many sections
- After Safe/Balanced setups are stable
When to turn it off
- Content below the fold appears blank until scroll and never paints
- Animation or sticky sections behave oddly
