Hello everybody we are building a DNN site which should fulfill all the W3C validations but as we have used dotnetnuke navigation skin object to show the menu in our site. Html rendered by the dnn navigation skin object is not validating w3c standards.
Below is html rendered by the dnn navigatin skin object.
<!--Top Menu Links Starts Here-->
<span><span width="100%" class="m_node" name="dnn$NAV2$ctlNAV2" id="dnn_NAV2_ctlNAV2" orient="0" sysimgpath="/aruba/images/" imagelist="[0]TopMenu_Home.gif,[0]TopMenu_Explore.gif,[0]TopMenu_People.gif,[0]TopMenu_Vacation.gif" imagepaths="/aruba/Portals/0/" css="m_node" mbcss="m_control" mcss="m_s_container" postback="__doPostBack('dnn$NAV2$ctlNAV2','[NODEID]~|~Click')" callback="dnn.xmlhttp.doCallBack('ctlNAV2 dnn_NAV2_ctlNAV2','[NODEXML]',this.callBackSuccess,oMNode,this.callBackFail,this.callBackStatus,null,null,0);"></span></span>
<!--Top Menu Links Ends Here-->
W3C validation error
there is no attribute "width".
… <span><span width="100%" class="m_node" name="dnn$NAV2$ctl
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.
How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.
