this is a error form html validation error i don't know what is this any body tell me what is this .
document type does not allow element "div" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag
This is a code;
<a href="callback.php" class="nyroModal"><div id="buttion"></div></a>
and here is a description of error.
The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
i'm waiting for the solution .
