# section.level1.properties

Properties for level-1 sections

## Description

The properties that apply to the containing block of a level-1 section, and therefore apply to the whole section. This includes `sect1` elements and `section` elements at level 1.

For example, you could start each level-1 section on a new page by using:

    <xsl:attribute-set name="section.level1.properties">
      <xsl:attribute name="break-before">page</xsl:attribute>
    </xsl:attribute-set>

This attribute set inherits attributes from the general `section.properties` attribute set.
