问题 I have the impression that the use of javascript often breaks W3C xhtml/css validity. Is this true? If so, why and is there a way for me to use javascript in my webpages and still have them be W3C valid (html, xhtml, css)? 回答1: If you wrap your javascript in a //<![CDATA[ tag it will validate https://developer.mozilla.org/en/properly_using_css_and_javascript_in_xhtml_documents 回答2: The answer of your question is yes.

问题 Image I have an element like this <someElement a="" b="" number="1" scale="meters"><child/></someElement> scale and number always appear together but they are not defined in one exclusive element. When unmarshalling the someElement element to a SomeElement java instance I want a single member in the SomeElement class to represent number and scale . At the moment both number and scale are attributes and then the afterUnmarshall() method is used for calculating one number. Is there a way to do

问题 I have tried everything to remove the default down arrow button from the the SELECT element, but couldn't succeed yet. I have also tested the background image, that shows behind the default button. And even tried by making NONE as Background, but it's not working for me. How can I style a select element so the arrow does not appear? 回答1: It's impossible to do in all browsers (reliably) without a JavaScript workaround. Not to mention, if you're not careful it will provide a bad UX. The one I

问题 I'm reading the RDF Schema 1.1 recommendation, which includes the following (emphasis added): 5.1.2 rdf:Bag The rdf:Bag class is the class of RDF 'Bag' containers. It is a subclass of rdfs:Container. Whilst formally it is no different from an rdf:Seq or an rdf:Alt, the rdf:Bag class is used conventionally to indicate to a human reader that the container is intended to be unordered. 5.1.3 rdf:Seq The rdf:Seq class is the class of RDF 'Sequence' containers. It is a subclass of rdfs:Container.

Recently I noticed my live instance of a web app I'm developing saved to the dashboard of Chrome, and the "screenshot" cover image used showed my page just as the loading screen was

问题 I read about CSS2.1 Specification, and in "Anonymous inline boxes" section, it shows an example of anonymous inline boxes like this: <p>Some <em>emphasized</em> text</p> and it says: the <p> generates a block box, with several inline boxes inside it. The box for "emphasized" is an inline box generated by an inline element (<em>), but the other boxes ("Some" and "text") are inline boxes generated by a block-level element (<p>). The latter are called anonymous inline boxes because they do not

问题 I'm trying to understand a behavior I've seen when I was messing around with some html code you can see here. You'll notice that if you change the following: <div style="border: solid 1px black;"> <div style="margin-top:50px;"> Post Title </div> </div> to this (ie. "border: solid 1px black;" to "border: solid 0px black;"): <div style="border: solid 0px black;"> <div style="margin-top:50px;"> Post Title </div> </div> the margin of the inner div does not effect the outer div any longer.
