I have SharePoint custom form with jquery tabs for some reason the sharepoint datefield is so small you can't see it even though it has width specified width. It shows as a small box about the size of a checkbox. I copied just the specific section from the form.aspx file. I am using jquery tabs. Request Date is the field in question.
<xsl:template name="dvt_1.rowedit">
<xsl:param name="Pos" select="position()"/>
