问题 In HTML5/JavaScript, if I create a namespaced dom node programmatically, like so: svgElt = document.createElementNS("http://www.w3.org/2000/svg", 'svg') the node 'knows' it's own namespace, which I can retrieve like so: svgElt.namespaceURI // result: "http://www.w3.org/2000/svg" But the namespace is not treated as a "normal" attribute: svgElt.getAttribute('xmlns') // result: null So the behavior of the programmatically created node is different from the equivalent "straight" node <svg xmlns=

问题 The XHTML 1.1 modular specification https://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd references various modules which, in turn, reference other entities, in all pulling in entity reference definitions, DTDs, etc. In addition other DTDs such as https://www.w3.org/2002/04/xhtml-math-svg/xhtml-math-svg.dtd pull in all sorts of MathML and SVG entities, which in turn reference other entities. Is there some place that simply lists all the XHTML/MathML/SVG entities by public ID (e.g. -//W3C//ELEMENTS

问题 Is there a way to force to iPhone’s Safari to use media="handheld" in place of media="screen" ? 回答1: You can't.

For example, for images or stylesheets. I am able to use this method to successfully generate a text-based document, but I need to understand
