Scroll Snap Challenges

Though JS-free fixed table row and column headers have been possible for quite some time, Safari’s and Chrome’s recent fixes got some people pretty excited. Enough that folks are copying code samples in whole, without always paying attention to necessary considerations. That same excited demo included other CSS properties that…

Embracing Design Constraints

Form ever follows function. Louis Sullivan Louis Sullivan, the father of the modern skyscraper, espoused this belief throughout his work. He recognized that the purpose of the building, when entering a place with no prior art, had to drive how it would look. With both the technology and audience providing…

More Accessible Skeletons

I had this post queued up for Halloween because, come on, skeletons, and then life did its thing and now it is a … Thanksgiving post? Many skeleton patterns do a poor job presenting themselves to screen reader users in any meaningful way. They often stuff aria-busy into their widget,…

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.

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…
