The title of this post might seem a little surprising. Isn't alternative text supposed to describe the image?
That's the concept that's drilled into us, and it's what most people think of when writing alt text. However, in some situations, it's actually wrong. One of those situations is when the image is serving as the visible content of a control, such as a link or button which does not also…

Weird little accessibility note: using the CSS property display: table causes NVDA to announce the element as a table. (I'm not sure about other screen readers).
Putting role="presentation" on the element with this property stops it announcing as a table.
This is yet another reason you're better off using Flexbox or Grid for layout (as if we needed any more reasons). They're a lot more…

WCAG Success Criterion 1.4.4 Resize text states:
Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.
The reason for this is pretty obvious: people with low vision may need to resize text so they can read it. There are two ways to do that in the browser (not counting tools like screen magnifiers,…

Recently CSS Tricks posted "A Deep Dive on Skipping to Content" by Paul Ratcliffe. It's great to see so much content lately focused on accessibility, and this article should prove useful for many years to come.
However, I've got a few thoughts on the implementation which I think can improve it a bit, related to the skip link target element. I posted some of these as a comment on the article, but…

I came across a weird issue while doing an accessibility audit recently. NVDA announces the site logo as "clickable", and the cursor changes to a pointer (the little "hand") when hovering over it with the mouse. I assumed it was a link to the homepage, as is typical for header logos, but clicking it did nothing – on the homepage, at least.
On interior pages, clicking the logo takes you to…

I really appreciate when a website or app offers the choice of dark mode. It makes reading at night much easier on the eyes, and some people prefer it at all times due to vision issues.
I'd never implemented a dark mode switch, so one of my goals for my blog redesign was to do so, both for reader convenience and to gain the experience. Here's how I did it.
It might seem surprising that I discuss…

Several years ago when I was working at Romni Wools, a yarn shop in downtown Toronto, I was asked to make a sample from the then-new Malabrigo Twist yarn. I found this pretty Shetland Eyelet lace pattern in Barbara Walker's A Treasury of Knitting Patterns (page 179), which worked up nicely into a hat.
This hat requires 100 grams of aran weight yarn (the sample used 55 grams/83 yards, so even if…

I guess I'm a little obsessed with the Group module, or maybe it's just that I've been using it a lot lately, and still learning its ins and outs.
One of the main purposes of Group is to control user access to various content types, based on what Group(s) the viewing user and content are in. Each Group type has an extensive permissions table where you can control permissions for anonymous users,…

Previously, I posted about how to create a view on a user's profile of content authored by that user, limited to content in Group(s) the viewing user is a member of. That tutorial shows how to accomplish that with a view of content (Drupal nodes) which are in Groups.
The person who requested that tutorial later told me they needed a view of Group content. Group content is the relationship between…

The following preprocess function will give you unique classes on the body tag for each Group content type (from the Group module). It adds two classes, one that includes the Group type that the content is in as well as the Group content type (e.g. group-content--client-group--node-page); and one with just the Group content type (e.g. group-content--node-page).
Place this code in your theme's .…
