to make valid: xhtml twitter cards facebook-graph-api for http://www.theyact.com/acting-classes/los-angeles/ I've managed to get my code to come up valid everywhere... save 1 error on http://validator.w3.org/ there is no attribute "property" but only 1 instance among the many in the code, only the below seems to ruffle the validator's feathers: <meta name="og:description" property="og:description" content="... I'd like the code to be completely valid in validator.w3.org's eyes. What am I missing? unor If you remove this element, the validator will complain about the next one containing the

Are single quotes valid in HTML/XHTML?

Are single quotes valid in HTML? And more specifically: XHTML strict. <table width="100%"> <table width='100%'> Yes, single quotes are valid. From the XML spec: [10] AttValue ::= '"' ([^<&"] | Reference)* '"' | "'" ([^<&'] | Reference)* "'" A source of confusion on this matter seems to come from this article, http://www.javascriptkit.com/howto/xhtml_intro.shtml which seems to claim that single quotes are not valid in xhtml. However, since no specification is cited, and since the article also claims that lowercase names for attributes and elements are forbidden, the author may merely be

XHTML won't validate && and < in a JavaScript function

由 自闭症网瘾萝莉.ら 提交于 2019-11-27 17:42:26
问题 Here's the snippet of code that won't validate: if (user_age > 15 && user_age < 91) It gets the following errors: XML Parsing Error: StartTag: invalid element name and XML Parsing Error: xmlParseEntityRef: no name The first error is thrown for the "less than" and the second one is thrown twice, once for each ampersand. Replacing the above signs with & and < validates fine, but of course it completely ruins the function. 回答1: Or you can protect the script from the xml validation like this:

Nest lists in paragraphs in html

由 烈酒焚心 提交于 2019-11-27 07:39:03
问题 It seems that (strict) html doesn't allow nesting any non-inline elements inside a <p> , but then how am I supposed to render a paragraph that contains a list (something that occurs often in natural texts). I've seen three answers that all seem unsatisfying: Lists should not happen inside paragraphs. (I'm not going to go into a cultural debate, but I certainly hope that html is not going to become the place to dictate writing style.) Separate the text into a paragraph, then a list, and then a
