Description for second item is not displaying completely as like the first item in CQWP when using itemstyles. The below custom itemstyle i have used.
<div class="Corpdescriptionstyle" style="height:200px;">
<xsl:value-of select="substring(@Description, 0, 690)" disable-output-escaping="yes" />
<a href="{$SafeLinkUrl}">..more</a></div>
</td>
</tr>
