# up.RenderResult.prototype.none

Whether this render pass did not result in any fragments being rendered.

There are some cases where no fragments were rendered:

- The server sent HTTP status `304 Not Modified` to [avoid re-rendering unchanged content](https://unpoly.com/learn/conditional-requests.md).
- The server sent HTTP status `204 No Content`.
- The target selector was set to `':none'` by either client or server.
- The server sent an [`X-Up-Accept-Layer`](https://unpoly.com/api/X-Up-Accept-Layer.md) or [`X-Up-Dismiss-Layer`](https://unpoly.com/api/X-Up-Dismiss-Layer.md) header. This [closes an overlay](https://unpoly.com/learn/closing-overlays.md#from-server) before content is rendered.
- Every targeted element was [kept](https://unpoly.com/learn/keeping-elements.md) by [`[up-keep]`](https://unpoly.com/api/up-keep.md).
