right and if you lower case HTML = html the error goes away

'Section lacks heading' invalid for aside/section/header


Validating the following generates the error 'Section lacks heading'...

<!DOCTYPE html>
<title>XHTML5 Test</title>



<header><span>Search Website...</span></header>
<div><span>The sidebar, <em>not</em> to be inside an article element.</span></div>



It seems more logical to accept the generic 'header' element as a valid header for sidebar section elements.

Incorrect checking for HTML5 <IFRAME> WIDTH as percent

I am trying with minimal success to add an iframe map to my new HTML5 webpage

Whilst trying to establish why my iframes do not display I got this checking error ...

Validation Output: 1 Error

Line 66, Column 111: Bad value 95% for attribute width on element iframe: Expected a digit but saw % instead. …me/N151.12061,6.11309,-3.06282,48.19144/Z8/" width="95%" height="200"></iframe>

This conflicts with the information on where it says ...

Iframe - Set Height and Width

Use the height and width attributes to specify the size.
The attribute values are specified in pixels by default, but they can also be in percent (like "80%").

My knowledge may be incomplete as in - it is NOT permitted to do % from HTML5 - but it would be nice to know either way which is correct.

Meantime, I'm off to try to do it CSS ....

Thanks for your attention.

UTF-8 Errors on file upload, not by URI

I'm trying to validate If I run a scan by URI or by direct input, the scan runs as expected. However, when the HTML source is saved in a file and uploaded, this error is reported on line 651:

"The error was: utf8 "\xED" does not map to Unicode" and the scan doesn't run.

The specific character in question:

If this character is removed, it fails on the fancy character in "traducción" -- it's not just the character above. The encoding of the page is UTF-8 and it is saved as UTF-8 before being uploaded. The scan works when the encoding is set to UTF-16, but not when it reads UTF-8 from the HTML.

Can anyone provide any advice here? We have an automated system that downloads web pages and runs them against our local validator via a file upload and this page won't scan due to this error. Is the encoding set improperly on the web page? Am I missing something else here?

Thanks for your time and work,

Web Service

As part of my teaching web development in our Computer Science program, I use my own course management system that allows student exercise uploads and display of their solutions both in the browser and in syntax highlighted fashion. I can have the program automatically fed into your validator which shows the full report. However, it would be really nice if I could just fetch back a list of errors which I could display in my system beside their solution.


Do you have or are you interested in providing a web service where a page could be passed in as a parameter and a compact error list retrieved as output? The compact list would not be a verbose as the full report but list only the error message, a line number, and a highlighted part of their source. Perhaps the output would be an HTML table?


Just a thought… Thanks for your service; it is great.

[VE][html5] The itemprop attribute was specified, but the element is not a property of any item



While validating our website we received error “The itemprop attribute was specified, but the element is not a property of any item” this is because we added “itemprop”. We added the following meta:


<meta itemprop="name" content="Myzeal It Solutions" />

<meta itemprop="url" content="" />

<meta itemprop="type" content="website" />

<meta itemprop="image" content="" />

<meta itemprop="title" content="End to End Business IT Solutions-Offshore Software Development Provider-Web Application Outsourcing Company India-Independent Software Testing-MYZEAL IT Solutions." />



This is our business requirement and we cannot remove this.


Kindly suggest what else we need to do to fix this.

Validation Error - Social Buttons

I did the Markup Validator, and it quickly replied that and error was found while checking this document as html5. There were 15 errors and 5 warnings for my site: 

Then i did the Link Checker, this took a little longer and showed some errors, but they were different and much less alarming. I guess my question is, do these errors devalue my site? Most of the errors have to do with the favicon and the social media buttons.

[VE][html5] Add Subject Here

I have received the error:

“& did not start a character reference. (& probably should have been escaped as &amp;.)”

But the & was part of a url within a href=””, I am thinking there should be an exception for this?

Error [html5]: ""

Thanks for the validations J
