Beginner. I have created a custom template for a CQWP in the ItemStyle.xsl. One thing that I am not sure about is how I could associate a css file so that anytime this template style is used the results are rendered the same way. Is there a good approach to this, or can I even do it?
Reference the CSS file in the masterpage being used on the site.
Open your masterpage in SharePoint Designer and add this line in the header tag:
<SharePoint:CssRegistration runat="server" name="path to css file" after="corev4.css" />
