Attribute ddata-horizontalposition not allowed on element li at this point- w3c validator

Question

w3c validator shows this error:

Attribute ddata-horizontalposition not allowed on element li at this point.

<li data-text-id="#bannerscollection_kenburns_photoText4" ddata-horizontalPosition="center" data-verticalPosition="center" data-initialZoom="1" data-finalZoom="1"></li>

Someone please help me

Answer 1

The attribute ddata-horizontalPosition is not allowed in HTML5.

It probably should be

data-horizontalPosition="center"

See http://www.w3.org/TR/html5/dom.html#embedding-custom-non-visible-data-with-the-data-*-attributes .

Answer 2

尝试一下：

<li data-text-id="#bannerscollection_kenburns_photoText4" data-horizontalPosition="center" data-verticalPosition="center" data-initialZoom="1" data-finalZoom="1"></li>
