Hello,

according to the HTML Standards ID-Attributes of any HTML Tag in a webpage have to be unique in the document!?

Does this rule also apply to HTML Tags that have been "disabled/hidden" by using: display:none?

Example:

<html>
<body>
<div id="one"></div>
<div id="one" style="display:none;"></div>
</body>
</hmtl>

Is this valid HTML or not. So the question is do "display:none"= hidden Elements also "count/matter" in regard to the rule only having unique ID-Attributes in a single webpage?

Thanks Jan
