accessibility

问题 I'm wondering about screen reader accessibility using Twitter Bootstrap framework and FontAwesome icon fonts. I'm looking at 2 different icon situations: 1) The icon has helper text that a screen reader will pick up: <a href="#" class="btn btn-default" role="button"><span class="fa fa-pencil"></span> Edit</a> 2) And a standalone icon without any helper text: <a href="#" class="btn btn-default" role="button" title="Edit"><span class="fa fa-pencil"></span></a> Ideally, in both situations, a

问题 This is my first time posting here, but I have found this site an invaluable repository for many years. I have recently been adding tooltips to a website form. Initially, my concern was to make these work when a mouse-user hovers over the tooltip icon (in my case simply '(?)'). I was using the following CSS: .tooltip { border-bottom: 1px dotted #000000; color: #000000; outline: none; cursor: help; text-decoration: none; position: relative; } .tooltip span { margin-left: -999em; position:

问题 i work at a place where we build applications that process and store sensitive data. we have 3 environments. Dev, UAT / QA (user acceptant testing) and Production the developers at my work have no access to UAT or Production and have limited access to Dev. All we can do in dev is connect to a dev DB server . we have no access to the dev server itself. so we arent allowed to play with things like the web server (iis) on dev. if we want changes we must go though a formal process of submitting

问题 If for presentational purposes one needs to separate a word with span s or other inline elements, does a screenreader still read the whole word? Example: <code>span</code>s or Forscher<span class="gendered">In</span> 回答1: Generally screen readers don't pause in this case. However, if a user enables font changes and/or colors reporting, it might cause interruptions like this: Consolas span Arial s for <span> s. That's because the code segments are rendered with Consolas font here at

问题 How can you add an 'alt' tag to tile layers, and raise the accessibility score of an application, in particular to the Esri.WorldGrayCanvas , but any of the tiles found at http://leaflet-extras.github.io/leaflet-providers/preview/? 回答1: You could manipulate the tile images when they load by hooking into the tileload event: esriGray.on('tileload', function (tileEvent) { tileEvent.tile.setAttribute('alt', 'Map tile image'); }); That way the images always have the alt tag, even after zoom/pan

问题 I have winforms application that contains cefsharp ChromiumWebBrowser component. I want JAWS to read it's content. Now JAWS only read title of main window. Is there any way to achieve this? I tried "force-renderer-accessibility" flag but it didn't help me. Here is the code i tried: var settings = new CefSettings() { CefCommandLineArgs = { new KeyValuePair<string, string>("force-renderer-accessibility", "true") } }; Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler:

问题 I'd like to allow a user to press a button directly from my app and read what's on the screen using VoiceOver. Right now, my only option is bundling recordings of each page and just playing them when the user presses the button. VoiceOver would really simplify this process. Is it possible? Thanks! Thomas 回答1: No, for more info on someone who wanted to do something similar see this link 回答2: You could use this if (UIAccessibilityIsVoiceOverRunning()) { UIAccessibilityPostNotification

问题 How do I override the accessibility feature in mathjax that puts a blue box around equations? I just want it to respond like normal text when clicked, ie no blue box. For example, click on an equation here: http://jsfiddle.net/dandiebolt/AqDCA/ \(ax^2 + bx + c = 0\) 回答1: You are probably describing the native browser behavior that adds an outline to an element that is in focus (default styling depends on the browser). MathJax elements can be put into focus by clicking because they are added

问题 I am trying to retrieve accessible information from a standard VCL TEdit control. The get_accName() and Get_accDescription() methods return empty strings, but get_accValue() returns the text value entered into the TEdit. I am just starting to try to understand the MSAA and I'm a bit lost at this point. Does my TEdit need to have additional published properties that would be exposed to the MSA? If so would that necessitate creating a new component that descends from TEdit and adds the
