You have used the element named above in your document, but the document type you are using does not define an element of that name. This error is often caused by:
For most tags, the reason is that there is other ways to achieve the same result with standard tags or with CSS.
![]() | <nobr>there is no wrapping here</nobr> |
![]() | <table><tr><td nowrap>there is no wrapping here</td></tr></table> <span style="white-space: nowrap;">there is no wrapping here</span> |
NOBR is not approved by the W3C; <nobr> turns off wordwrapping between the start and end NOBR tag. There are several ways to replace a NOBR with a standard tag :
![]() | <object width="400" height="300"><param name="movie" value="movie.swf"/>
<embed src="movie.swf" width="400" height="300"/> </object> |
![]() | <object width="400" height="300" type="application/x-shockwave-flash" data="movie.swf">
<param name="movie" value="movie.swf" /> </object> |
EMBED does not exist in HTML. It is a proprietary tag.
Replace the tag with the equivalent in standard HTML.
