The following Newsgator syndication/button code inside my Wordpress Sidebar template is offending to W3C: <li><a href="http://www.newsgator.com/ngs/subscriber/subext.aspx?url=http://www.a1-outdoors.com/outblog/?feed=rss2"><img runat="server" src="http://www.newsgator.com/images/ngsub1.gif" alt="Subscribe in NewsGator Online" border="0" /></a></li> -saying that the document type I am using does not support the attribute "runat". I am wondering if this is related to the Doctype on the header template: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> My knowledge is next to nil, so before I go and do something to completely fry my blog, would replacing the above doctype with: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> Make this a "transitional" doctype which should allow the runat attribute inside the sidebar template/newsgator syndication code, and therefore pleasing to W3C? Thanks, Paul
