w3c markup validation: Attribute duration not allowed on element li at this point

Question

I'm getting this error when I validate through w3c validator:

Attribute duration not allowed on element li at this point.

<li data-text-id="#bannerscollection_kenburns_photoText3" data-horizontalPosition="center" data-verticalPosition="center" data-initialZoom="1" data-finalZoom="1" duration="5" >

Somebody please help me. Thanks in advance

Answer 1

试试这个代码：

<li data-text-id="#bannerscollection_kenburns_photoText3" data-horizontalPosition="center" data-verticalPosition="center" data-initialZoom="1" data-finalZoom="1" data-duration="5" >

Answer 2

As the message says, the attribute duration is not allowed for the element li , as you can easily check in the specification :

Content attributes:

• Global attributes
• If the element is a child of an ol element: value

duration is not a global attribute .

You could prefix it with data- , as you do it with all the other attributes, too. But then, if you use a third-party tool that needs a duration attribute, it would not work anymore. (You didn't say anything about a tool in your question, though.)
