w3c

问题 I'm wondering what are the differences between the mechanisms in JsonWireProtocol ( Status: OBSOLETE ) and W3C Living Document from 31 December 2019 ( the new standard ) when using Selenium for UI tests. I know that Selenium have used the following: When we make a new instance of a driver (C#): using OpenQA.Selenium; using OpenQA.Selenium.Chrome; IWebDriver driver = new ChromeDriver(); we actually make a POST /session request to the selenium server. After that via JsonWireProtocol and, in

问题 From W3C's Dynamic rows and column effects This collapse value causes the entire row or column to be removed from the display, and the space normally taken up by the row or column to be made available for other content. From above what I understand is that if I do something like the snippet below, the result should be something like: But instead it shows like: table tr td { visibility: collapse; } .red { background-color: red; } /* All the below don't work as well. */ table tr td:first-child

问题 When the default namespace and a prefixed namespace resolves to the same namespace URI, why is an attribute with no prefix not equal to a prefixed attribute, when both have the same local name? The "Namespaces in XML" specification just says it's so, but it's very short on why. Anyone knows why it's like this? Excerpt from section "6.3 Uniqueness of Attributes" at http://www.w3.org/TR/xml-names11/#uniqAttrs : For example, each of the bad empty-element tags is illegal in the following: <!--

问题 i'm need to convert an xml build with dom4j to w3c document and don't have any idea about how do it... 回答1: I'm assuming you want to go from: org.dom4j.Document To: org.w3c.dom.Document From the dom4j quick start guide: Document document = ...; String text = document.asXML(); From a JavaRanch example on String to Document: public static Document stringToDom(String xmlSource) throws SAXException, ParserConfigurationException, IOException { DocumentBuilderFactory factory =

问题 I've been studying the W3C format log files in IIS 7.5 for a while on a server with some performance issues, and it seems to me that, contrary to MSDN documentation, the "time" field is not "the time, in Coordinated Universal Time (UTC), at which the request occurred" ... but rather it is the time at which the response was finished being sent. I say this because when I track the sequence of page request from users in a somewhat controlled environment, they would have to be going back in time

问题 Consider the main axis and cross axis of a flex container: Source: W3C To align flex items along the main axis there is one property: justify-content To align flex items along the cross axis there are three properties: align-content align-items align-self In the image above, the main axis is horizontal and the cross axis is vertical. These are the default directions of a flex container. However, these directions can be easily interchanged with the flex-direction property. /* main axis is

问题 According to MDN, POST requests are not preflighted if the Content-Type is any of application/x-www-form-urlencoded , multipart/form-data , or text/plain . But isn't multipart/form-data exactly as unsafe as application/xml ? For instance I would expect cross-origin POST requests to the url http://bank.com/money-orders/ to always be disallowed, regardless of the content type the endpoint accepts. 回答1: Because: Before CORS was ever even conceived of, it was possible to send a cross-origin POST

问题 TL;DR According to the spec the following should not work but it does: .a .b + .b {margin-top:20px;} Details According to the spec the "Next-sibling combinator" (or "adjacent sibling combinator") should only work for "sequences of simple selectors", which themselves are defined as ... a chain of simple selectors that are not separated by a combinator. In my example given above, the selector .a .b to the left contains a "descendant combinator" (represented by whitespace) and should therefore
