属性属性的Html验证错误 [英] Html validation error for property attribute
问题描述
我使用的是少数Facebook社交插件,我正在使用meta标题。验证页面时,W3C验证器抛出错误 - >错误:没有属性属性。
我使用的是XHTML Transitional doctype - <!DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
建议如果我必须将doctype改为别的。
Facebook的插件使用基于RDFa的 Open Graph ,它的RDFa增加了属性
属性为元素,如果没有这个添加,纯HTML没有这样的属性(如果你问我,添加一个没有命名空间的属性是一个奇怪的设计,重复使用< meta>
标记的一半,但没有人做过。)
验证XHTML-with-RDFa,你需要DOCTYPE:
<!DOCTYPE html PUBLIC - // W3C // DTD XHTML + RDFa 1.0 // ENhttp://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd\">
这意味着您必须编写有效的XHTML 1.1。 更多
I am using few facebook social plugins and I am using the meta header. When validating the page, the W3C validator is throwing the error -> "Error: there is no attribute "property".
I am using the XHTML Transitional doctype - <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Pls Suggest if I have to change the doctype to something else.
Facebook's plugins use Open Graph, which is built on RDFa. It's RDFa that adds the property
attribute to elements. Without this addition, plain HTML has no such attribute. (If you ask me, it's a strange design to add a new attribute without namespacing it, and to re-use half of a <meta>
tag. But no-one did.)
To validate XHTML-with-RDFa, you'll need the DOCTYPE:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">
This means you will have to be writing valid XHTML 1.1. More
