HTML issues tagged as property.
A <meta>
element has an invalid value for the property
attribute, probably caused by invalid double quotes. Check out the double quotes, ”
should be "
.
The correct markup for this meta tag should be like:
<meta property="og:type" content="website" />
A <meta>
element without a content
, itemprop
or property
attributes has been found in an unexpected place.
Check its attributes and context - depending on the section of the document (<head>
or <body>
), the <meta>
element allows different attributes.

A <meta>

. Example of a valid meta
tag:
<meta name="description" content="Description of the page" />
A <meta>
element without a itemprop
or property
attributes has been found in an unexpected place.
While the <meta>
element is commonly used within the <head>
section of the document, it can also be used within the <body>
section, for example in the context of defining microdata, as in this example:
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
Price: $<span itemprop="price">1.00</span>
<meta itemprop="priceCurrency" content="USD" />
</div>
When used within the <body>
section, the <meta>
element is required to have a itemprop
or property
, and a content
attribute, and it can’t have a http-equiv
or charset
attribute.
A common cause for this issue is including a <meta>
element that was intended for the <head>
section (for example one containing a http-equiv
attribute in the <body>
, for example:
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<form>
...
</form>
