Copy the template <xsl:template match="section" from
html/sections.xsl to your customization layer, and
change the top of it from:

<xsl:template match="section">
  <xsl:variable name="depth" select="count(ancestor::section)+1"/>

  <div class="{name(.)}">

to:

<xsl:template match="section">
  <xsl:variable name="depth" select="count(ancestor::section)+1"/>

  <div class="{name(.)}_{$depth}">
