Responsive Progressive Accessible Vanilla Search

I received a design for a project recently that called for a search field hidden behind a single icon — no visible label text, no visible field, no submit button. While I’ve seen this pattern on sites repeatedly, I feel they generally get it wrong. Relying on bloated HTML and…

Ganesha may or may not be stealing chocolate from the advent calendar. For a few years now web developers around the world have celebrated Saturnalia Christmas with advent calendars covering topics related to the web. Some come and go, but you’ll probably recognize a few regulars on this list. I…

Gitter a11ySlackers Sidecar

Animated image of the Gitter sidecar with the a11y Slackers channel embedded on my site. If you are unfamiliar with the a11y Slackers channel on Gitter, I encourage you to read Steve Faulkner’s post, Anybody can be an A11y Slacker. Essentially it’s an alternative to the accessibility channel on Slack.…

Addendum to “The State of Airline Websites” at Smashing Magazine

Last week Smashing Magazine published a lengthy and detailed post titled The State Of Airline Websites 2015: Lessons Learned. While it was an impressive dive into the user experience of each site covered, it left out any aspect of accessibility. Surprising perhaps no one, I got as far as reading…

NFL Raises Colorblind Awareness

Not intentionally, of course. Images captured using the Chromatic Vision Simulator app on my phone. The last two images show three different kinds of colorblindness each: protanopia, deuteranopia, and tritanopia. The NFL provided a great and highly visible (pun!) case study in how colorblindness affects people and, given football’s wide…

Be Wary of Add-on Accessibility

I update this post regularly, but on June 30, 2020 I wrote #accessiBe Will Get You Sued, where I demonstrate that accessiBe’s product generates more testable errors and creates a worse experience. I also document paid news stories, deleting critical comments, and its efforts to undermine WAVE. There is an…

HTML Source Order vs CSS Display Order

Last month in my post Source Order Matters I wrote about why we need to consider how the source order of the HTML of a page can affect users when the CSS re-orders the content visually. While I used a recipe as an analogue and cited WCAG conformance rules, I…

Slides from “Selfish Accessibility” at Google

Or view the slides directly at SlideShare The kind folks at Google made a video of my talk and posted it to YouTube. I’ve also embedded it below: I was treated to lunch at a few of the cafes and cafeterias around the office, including a food truck parked on…

My Slides from Accessibility Camp Toronto 2015

You can also view the slides directly at SlideShare. Sadly, the animated GIFs in my presentation did not survive the conversion to SlideShare. I’ve added them at the bottom of this post, but they are all quite large and will take time to load. If you want to save on…

Google’s AMP HTML

Google wants to speed up the web, and it has a plan: For many, reading on the mobile web is a slow, clunky and frustrating experience – but it doesn’t have to be that way. The Accelerated Mobile Pages (AMP) Project is an open source initiative that embodies the vision…

Don’t Disable Zoom

Codepen demos showing a page zoomed and a page that has disabled zoom on mobile. A handy feature of mobile browsers is the ability to zoom into a page with a simple gesture. A less handy feature is the ability to override that. Ultimately this is bad for users. Sadly,…
