问题 This question already has answers here : What does “href” stand for in HTML? (4 answers) Closed 6 years ago . After writing html for couple of years I realized that I don't really know why the href attribute is named "href" . The HTML Recomendation does not shed light on the subject by saying : This attribute specifies the location of a Web resource, thus defining a link between the current element (the source anchor) and the destination anchor defined by this attribute. Also the HTML 4.01

问题 I'm trying to do xpath queries over an xhtml document. Using .NET 3.5. The document looks like this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> .... </head> <body> ... </body> </html> Because the document includes various char entities (   and so on), I need to use the DTD, in order to load it with an XmlReader. So my code looks like this:

How to get list of registered custom elements

问题 I'm trying to detect whether a custom element with a specific name was registered or not. Is there a way to make such check? Or is there a way to get list of registered custom elements? I do document.registerElement , but what else is there? Is it one-way API? 回答1: There is a way to check whether an element was registered. Registered elements have their own constructors, while unregistered ones would use plain HTMLElement() for constructor (or HTMLUnknownElement() whether the name is not

Why is an input tag not allowed directly within a form tag?

由 北城以北 提交于 2019-12-18 04:46:11
问题 I just read the following at http://w3fools.com/#html_forms: Non-block-level elements (such as <input> ) are not valid directly inside <form> tags until HTML5. I had never heard of anything along these lines, and every basic HTML tutorial I've seen seems to be just fine with putting input tags directly inside a form tag. So my question has three parts: Is the above statement legitimate? Why is this the case? (Was it simply an oversight, or were the creators of the HTML spec trying to prevent

What language types are allowed in the HTML script tag?

由 只谈情不闲聊 提交于 2019-12-18 03:04:09
问题 I was looking at the W3C specs for the script tag, and I noticed you can specify VBScript and TCL as a language type.

Why aren't other languages more commonly used, and is there a complete list of languages you can use within this tag? 回答1: You can put anything you want in there. That's the whole point of MIME types. The question is of course whether or not your user's browser can actually interpret it. But
