Web accessibility is an incredibly important topic, and should be considered as essential as subjects like security, UX (user experience), and design.

How To Get The Best Out Of WAI ARIA
WAI-ARIA (Web Accessibility Initiative - Accessible Rich Internet Applications), or ARIA for short, is a way of adding further accessibility to elements that you cannot by using HTML alone. Most usually it's used to add a label to something that assistive technology (such as screen readers) can access and present to the user, where the existing text inside the HTML is lacking or would be confusing…

The Affects of Covid on Web Accessibility
We've been a little over 2 years now with Covid in our lives, but there's still so much we don't know about it. One aspect of that is what the enduring effects of it are for some people, or Long-Covid as it is known. These effects vary in their symptoms and severity, but they can have an impact on our lives and can prevent us from doing all the things we are used to. Contents How Many People…

Picking The Right HTML Tag
Picking the right HTML tag can be difficult sometimes, which is probably why most of us tend to fall back to the generic <div> and <span> tags. Over time, this practice leads to Divitis, which makes code harder to read on more complex pages and it makes the web page less semantic, making it more difficult to navigate with assistive technology like screen readers. In-fact, ensuring we're…

Accessibility Concerns Over Chrome Removing Alert, Prompt, And Confirm Modals
Chrome has recently announced its intention to prevent cross-origin iframes from triggering the alert(), prompt(), and confirm() . These modals will still function for the top-level web page, and iframes within the same domain. Websites spanning multiple subdomains on the same domain will not allow these modals. These types of modals have been part of Javascript for decades and have seen their fair…

Accessibility Testing for Developers
If you're developing for the front end, then it's important to understand how to test that what you produce is accessible.

10 Simple Steps Towards Accessibility

While I don't always agree with that mindset as it can lead to a lazy approach to accessibility that's tacked on as an afterthought, I do understand that there is a real need for simple solutions that can fix the majority of problems.

Building an Accessibility Browser Plugin
I was recently talking with a former colleague about testing for accessibility, and specifically being able to run an automated test over a website to reduce the time needed to test. My answer then was that there is no way to fully automate testing for accessibility; there's no test that exists which can rubber stamp your website and give it passing marks. But it did give me an idea. Right now,…

Accessible Modal Dialogs
Modal dialogues are a part of the web whether we like them or not, and there's plenty of reason to not like them when they're implemented in a really intrusive way.

Accessible Tables
For many years, tables were the only tool available to lay out our websites as we wanted to achieve something that went beyond what you'd probably come to expect with your typical word-processed documents. Then for the last decade (or so) we were told that tables were evil, and using them was a sin that would earn us a spot in the 6th circle of IT hell. More recently we've learned that that anti-table…

Web Accessibility in Detail
The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect. Tim Berners-Lee When Tim Berners-Lee opened the WWW to the general public in 1991 (previously it was internal to the CERN network) he had a vision that it would be of use by all, and that tenet is as true today as it was nearly 3 decades ago. Back in the 90's, we had little…

Accessible Styled Form Elements
Since the inception of CSS, there's been one area of styling that has been a constant issue; forms. Simple elements, like <input type="text"> and <textarea> and buttons, have generally been ok, as borders, colours and fonts could all be set with standard styles that behaved as expected. Beyond that though, other elements were impossible to style consistently without either compromising…

Blind to Accessibility
When I first started learning about accessibility, I figured it was just enough to use alt attribute text on images, and use semantic tags.
