Alternative Text for CSS Generated Content

Relying on images that come from CSS has always been risky from an accessibility perspective. CSS background images, in particular, must either be purely decorative or be described to the user in some way. The risk is no different for images coming from CSS generated content using content: url(foo.gif) (typically…

Dialog Focus in Screen Readers

Creating an accessible dialog on the web is trickier than it should be. Lack of support for the <dialog> element, the need for fundraisers to get inert into WebKit, inconsistent support for the ARIA dialog role, and other annoyances make them problematic. Scott O’Hara has spent a few years covering…

Sortable Table Column Mad Libs

Visually and functionally sortable column headers on tables are straightforward (I have a post coming on that soon). However, making them accessible can be a bit frustrating. To clarify, making them accessible to screen readers is frustrating. There are two critical areas where screen readers fall down here: lack of…

Speech Viewer Logs of Lies

The headline is intentional hyperbole, chosen mostly for the sloppy alliteration. When sighted users test with a screen reader it is common to rely on the visual output — checking to see where focus goes, confirming that controls behave, watching the spoken output in a text log. The problem is…

When Is a Vetted Pattern No Longer a Vetted Pattern?

The moment you change it. As soon as you start to tweak the underlying code or aspects of the design, you run the risk of introducing bugs. That part should be easy for any developer to understand. The tougher part to get your arms around is that once you add…

I Don’t Care What Google or Apple or Whoever Did

Please do not use this post as an excuse to beat up the devs at Apple or Google. If you are doing that, you have missed the point of this post and you are being unnecessarily mean to individuals who may have no control over broader organizational decisions. Do not…

Block Links, Cards, Clickable Regions, Rows, Etc.

Whether you call them cards, block links, or some other thing, the construct of making an area of content clickable (tappable, Enter-key-able, voice-activatable, etc.) is not new. While hit area size is mostly a usability issue, marketers often want a larger click area around their calls to action (CTAs) to…

Link Targets and 3.2.5

TL;DR: Regardless of what accessibility conformance level you target, do not arbitrarily open links in a new window or tab. If you are required to do so anyway, inform users in text. Overview Throughout this post I am going to use the terms browser window and tab interchangeably. While they…

Defining ‘Toast’ Messages

In current user interface terms a toast is a message that appears on the screen; it is often short, often appears only briefly, and often animates up from the bottom (like a piece of ghostly yet precisely-crafted toast), though other directions and a fade-in/-out is common. The Name When Google…

My Priority of Methods for Labeling a Control

Here is the priority I follow when assigning an accessible name to a control: Native HTML techniques, aria-labelledby pointing at existing visible text, Visibly-hidden content that is still in the page, aria-label. Too often folks will grab ARIA first to provide an accessible name for a thing. Or they may…

Showing File Types in Links

Links to files can be a surprise for users, especially those who cannot use, do not notice, or do not have the status bar to show a link destination. Some users may appreciate knowing a link points to a file, sometimes even a particular file. For links with the download…

Responsive Type and Zoom

Typography that responds to viewport width (‘fluid’ or ‘responsive’ typography) can be useful when you want to ensure text does not get clipped or spill out of some design elements. Carousels, widget controls, or my Venn diagram are some examples. I say viewport width because I rarely see responsive type…
