w3c-validation

问题 I'm trying to describe a very basic metro train station map with stops and times. This RDF to Turtle converter can parse my XML, but the W3C validator throws: Error: Your document does not contain any RDF statement. I can't figure out why my document isn't valid because it isn't some very special use case? My blank nodes are described as Resource , according to the specification. Or do I have to use nodeID for multiple blank nodes? <?xml version="1.0"?> <rdf:RDF xmlns:rdf="http://w3.org/1999

问题 How can I remove the html <table> elements that are generated by the CreateUserWizard to validate the login page against HTML 5?

Can I do something get & work in

问题 Trying to get close a W3C validation of the output from my aspx (VB.NET 2008 Framework 3) I get this warning: Warning Line 6, Column 76: NET-enabling start-tag requires SHORTTAG YES </title><meta http-equiv="content-type" content="text/html; charset=utf-8" /> The sequence can be interpreted in at least two different ways, depending on the DOCTYPE of the document.

问题 I use a clear div in several places in a single HTML file, a la: #clear { clear: both; } usage: <div id="clear"> </div> But W3C's HTML5 validator appears to be complaining that each subsequent use after the initial use is a "duplicate ID": Why isn't this valid? How are you supposed to use clear divs multiple times on a single page if it isn't technically valid? Note: this is mostly just an informative question, my HTML renders fine on all modern browsers, and given that this is the only error

问题 I'm using HTML tables to create a timetable. Each row represents half hour, and the cells can span multiple rows by using rowspan . Sometimes I have empty tr elements, because all the slots are taken by cells from previous rows. In that case, the HTML validator complains: Row [N] of a row group established by a tbody element has no cells beginning on it. Sure, I could remove those empty tr and reduce the rowspan value of the expanded cells. But then the rowspan value would no longer
