Horizontal scrolling content at a height equivalent to 256 CSS pixels.Įxcept for parts of the content that require a two-dimensional layout for usage or meaning.ģ20 CSS pixels is equivalent to a starting viewport width of 1280 CSS pixels wide at 400% zoom.Vertical scrolling content at a width equivalent to 320 CSS pixels.Success Criterion 1.4.10 Reflow (Level AA): Content can be presented without loss of information or functionality and without requiring scrolling in two dimensions for: Relevant WCAG Criterion to help you fix it: You might have encountered this problem if you’ve ever tried to access a non-responsive website from a mobile device it’s annoying for all users. Magnifying content by 400% may require the user to scroll horizontally and vertically if the text does not reflow. Improper Content ReflowĪlthough reflow isn’t required for screen magnifiers, many low-vision individuals still use browser-based scaling tools. Unavailability of Focus Indicatorsįour Common Accessibility Issues for Screen Magnifiers 1. 1 Four Common Accessibility Issues for Screen Magnifiers.It might mangle page layouts less than the textZoom approach. bug 578179 - Option to wrap text to screen width (rather than container width) - this is an alternative to bug 611555, which change the Gecko core layout code to work more like the stock Android browser.bug 611555 - Should reflow on zoom (using textZoom-based reflow from the Easy Reading add-on).Get web sites to deliver Fennec as a mobile browser (evangelism to web developers UA string changes?).Spatial nav (makes it easier to select links and navigate menus at low zoom levels).Make sure that double-tap zooms to the right place and level.Zoom performance (speed, smoothness, responsiveness).Image rendering quality at different zoom levels. ![]() Other things that help mitigate reabability problems. In a sense, this is trying to get at the advantages of the android model without the obvious changes in layout. ![]() For example, we might use a default smaller size when fully zoomed out, but use a larger size when the user zooms in to read an article or have a minimum fontsize when the current element is 100% of the width of the webpage. What I mean by this is increasing the size of type when we can tell that it would be most useful, but not doing it when it would just really break the overall layout. We haven't explored the details of this very much, but we should start. It's a great additional feature to have, either as an add-on or built-in. This works really well, but it's too invasive to be our standard "make the page basically readable" functionality. Full-on page layout replacement, like Fabrice's Readability add-on.Because of this last bit, it's controversial, but I think we should try it. Cons: it changes a web-author's intended page layout (though, I think that any solution to this problem is going to require this to some degree). Pros for this approach: it definitely makes reader easier, and android users are used to it. Ben and Brad have a prototype of this in an add-on called Easy Reading. As a result, all solutions (that I know of) to the readability problem require "adapting" the page design intended by the site author. in many (most?) cases, though, the problem is with the design/layout of webpages themselves - they do not become easier to read through simple magnification, because by the time the text is big enough, the column of text is wider than the viewport. ![]() easier zooming (pinching) will help with the subset of readability problems that are just due to getting the right zoom-level.Right now, it's often hard to get an area of text into a font-size and element-size that is easy to read.
