阅读更多关于 W3C validator says 'feed does not validate' 'url must be a full URL'… whats wrong with it?

问题 Validating my feed, it has an enclosure with a URL of https://archive.org/download/NigelFarageAPersonalMessageToNorthernIrelandVoters./Nigel%20Farage,%20a%20personal%20message%20to%20Northern%20Ireland%20voters..mp3 I know it is a bit convoluted... but what is wrong with it? The stop in the directory name? the double dot in the file name? the comma? all of em? I have looked at the RFC on URL's but cant make it out(!). This feed does not validate. line 441, column 2: url must be a full URL:

Rails - Parameter with multiple values in the URL when consuming an API via Active Resource

阅读更多关于 Rails - Parameter with multiple values in the URL when consuming an API via Active Resource

问题 I am consuming an API that expects me to do requests in the following format: ?filter=value1&filter=value2 However, I am using Active Resource and when I specify the :params hash, I can't make the same parameter to appear twice in the URL, which I believe is correct. So I can't do this: :params => {:consumer_id => self.id, :filter => "value1", :filter => "value2" } , because the second filter index of the hash will be ignored. I know I can pass an array (which I believe is the correct way of

Opengraph W3C valid?

阅读更多关于 Opengraph W3C valid?

I would like to know if the opengraph markup is W3C valid, I'm getting the following error when I try to validate it: Line 14, Column 17: there is no attribute "PROPERTY" <meta property="og:site_name" content="sitename"> In case it's not valid, will it impact my pagerank and other search engines algo? Is it possible to cloak those properties? bobince It's not valid in the normal HTML doctypes, but there is a doctype you can use to validate XHTML documents including Open Graph: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd"> See this

HGROUP element removed from the HTML5 Specification. What alternative technique can be used instead?

阅读更多关于 HGROUP element removed from the HTML5 Specification. What alternative technique can be used instead?

As some of you would of heard the hgroup element is being removed from the HTML5 Specification . (For more info, see the W3C HTML Working Group's decision on request to drop hgroup from HTML5 on the W3C's Public Mailing List archives.) Now I'm currently working on the redesign of a site using this tag that creates a way of adding a sub heading. My current thoughts are to just add another hX tag under the main header, but I'm not sure if this would be semantic enough to do so. <h1>Darren Reay</h1> <h2>A developing web developer</h2> <p>Hello World</p> Could anyone either come up with a

W3C HTML validation for React JSX files

阅读更多关于 W3C HTML validation for React JSX files

When working on front-end projects I always like to work with linting tools. They prevent from dumb mistakes to serious smelly code pieces. Linting tools also suggest improvements and optimisations. Validating and linting HTML means using the W3C Validator. When working with vanilla JavaScript projects I use the grunt-html Grunt NPM module. And when working with Angular 1.x I use the grunt-html-angular-validate module, which is the same validator but adapted to Angular requirements (non standard attributes or incomplete HTML documents will not fire errors or warnings). However I have tried to

Can a label only refer to input elements?

阅读更多关于 Can a label only refer to input elements?

W3Schools have this to say about labels : The <label> tag defines a label for an input element. [Emphasis mine] Does this mean that the following HTML isn't valid? <!doctype html> <html> <head> <title>Example document</title> </head> <body> <label for="x">Label</label> <hr> <div id="q" contentEditable="true">Hello</div> <hr> <div id="x" contentEditable="true">World</div> </body> </html> Both Chrome and IE8 give focus to World when Label is clicked, Firefox does not. Which is correct? According to the W3C it applies to Form Controls, and Form Controls are defined as : Buttons Checkboxes Radio

Why was ::selection removed from the CSS Selectors spec, and how does its specificity work against type selectors?

阅读更多关于 Why was ::selection removed from the CSS Selectors spec, and how does its specificity work against type selectors?

Some questions about using CSS to specify the color of selected text: https://developer.mozilla.org/En/CSS/::selection says that, ::selection was drafted for CSS3 Selectors but removed from the current CSS3 draft. Anyhow, it's implemented in browsers and support will continue. Why was it removed? Imagine that a rule like the following exists in the default CSS that's implemented by the browser: ::selection { background-color: Highlight; color: HighlightText; } Further imagine that a rule like the following is defined in any site-specific authored stylesheet: body { background-color: white }

问题 I'm new to Scala, so I may be off base on this, I want to know if the problem is my code.

Correct way to include CSS after <head>

阅读更多关于 Correct way to include CSS after

Apparently adding <link rel="stylesheet" ... in the document body is considered a bad practice by W3C standards. The same for adding <style> blocks in the body... So are there any standard-compliant solutions to add CSS outside of the <head> tag? Like at the end of the document. If you only want to include your CSS styles on a specific events, there's nothing stopping you from doing so at the head: var linkElement = document.createElement("link"); linkElement.rel = "stylesheet"; linkElement.href = "path/to/file.css"; //Replace here document.head.appendChild(linkElement); This has the added
