# OPF-100: fixed-layout property on text, how to fix it

Source: https://epubcc.com/epubcheck/opf-100/ (updated 2026-11-04)

EPUBCheck OPF-100 is a usage message: “The "…" property only applies to pre-paginated content.” A property that only applies to fixed-layout (pre-paginated) content is set on reflowable content. It is a usage note (shown with -u), and the property is ignored there.

- Official message (EPUBCheck 5.4.0): The "%1$s" property only applies to pre-paginated content.
- Default severity: Usage

## Typical causes

- Fixed-layout settings such as page-spread-left or page-spread-right copied into a reflowable book.
- Spread properties on itemrefs of a book whose layout is reflowable.
- A template made for picture books reused for a text book.

## How to fix it

1. Read the property EPUBCheck names.
2. If the book is reflowable, remove the property from the itemref.
3. If the content really is fixed layout, declare it pre-paginated (rendition:layout) for the book or for that itemref.

## When it's not this

If an itemref has both page-spread-left and page-spread-right, that is OPF-011.
