You can use position() and mod on a per portlet basis because you are
calling apply-templates with a union of all the section and link
nodes.

If you named your styles using the convention back-white-0 and back-white-1

<xsl:template match="link">
<xsl:variable name="colour" select="../@colour"/>
<xsl:variable name="desclength" select="string-length(../description)"/>
<div class="back-{$colour}-{position() mod 2}">
LINK CONTENT
</div>
</xsl:template>
