Quick summary ↬
In a real money casinos nigeria short series of posts, we highlight some of the useful tools and techniques for developers and designers. Recently we’ve covered CSS Auditing Tools and CSS Generators, and this time we look into reliable accessible components: from tabs and tables to toggles and tooltips.
Table of Contents
Below you’ll find an alphabetical list of all accessible components. Skip the table of contents, or just scroll down to explore them one-by-one.
Every browser has default focus styles, yet out of the box, they aren’t very accessible. The goal of :focus is to give the user guidance on where exactly they are in the document and help them navigate through it. To achieve that, we need to avoid a focus that’s too subtle or not visible at all. In fact, removing outline is a bad idea as it removes any visible indication of focus for keyboard users. The more obvious the focus is, the better.
There are ways of designing better :focus styles. In her article Tips For Focus Styles, Nic Chan highlights a few helpful tips on how to improve focus styles with better affordance and a bit of padding, offset, and proper outlines. Sara Soueidan also published a helpful reference guide to designing accessible, WCAG-compliant focus indicators. The guide is aimed at both designers who want to learn about accessibility considerations, as well as developers who want to implement them. Need more fun with :focus styles? Lari Maza has got your back, too.
It’s important co consider the accessibility concerns around :focus-visible: as Hidde de Vries has noted, not all people who rely on focus styles use a keyboard and making focus styles keyboard-only takes away an affordance for mouse users too, as focus also indicates that something is interactive (thanks to Jason Webb for the tip!).
Finally, it’s worth noting that most recently Chrome, Edge, and other Chromium-based browsers stopped displaying a focus indicator (focus ring) when the user clicks or taps a button (thanks to Kim Johannesen for the tip!).
Every time you have to deal with a larger data set, be it a map, a data visualization, or just a country selector in checkout, autocomplete can boost customer’s input massively. But just as it helps with the input, it needs to help with announcing the options and the selection to the screen reader users as well.
Accessible Buttons and Icon Links
It’s not uncommon to have a link or button that visually has no text but consists only of an icon — a compact navbar, for example, or social icons. But how do you make sure that these kinds of icon links are fully accessible? As it turns out, it’s not as straightforward as one might think.
To show how we can do better, Kitty Giraudel dedicated an article “Accessible Icon Links” to the issue. They use an icon link consisting of an SVG with the iconic Twitter bird to illustrate the point, and shows step by step how to make it accessible: with a descriptive text that is visually hidden, then removing the SVG markup from the accessibility tree with aria-hidden, and, finally, correcting the fact that svg elements can be focused on Internet Explorer by adding the focusable attribute. At the end of the article, Kitty also shows how to turn all of this into a little React component.
A small detail that will make a huge difference for a lot of users.
In Creating Accessible Icon Buttons and Inclusively Hidden, Sara Soueidan and Scott O’Hara go into all the fine intricacies and details of icon buttons, exploring a number of techniques to make it work. Sara and Scott explore a number techniques, suggesting to use an appropriate technique for accessible visually hidden text — the text that will be visually hidden but accessible to screen readers. This could be done with a .sr-only utility class, or hidden and aria-labelledby, or aria-label alone. Sara wouldn’t recommend to use the SVG icon itself to provide a label for the button when I can provide one on the button itself directly.
In general though, there is still quite a bit of confusion which element to use for user interaction: when do we use links, and when do we use buttons? Marcy Sutton has written a detailed piece on Links vs. Buttons in Modern Applications. With a link, the visitor navigates to a real money casinos nigeria resource, taking them away from the current context. But a button prompts a change in the interface.
Marcy outlines use cases for both links and buttons in single-page applications, showing that a button is a perfect element for opening a modal window, triggering a pop-up, toggling an interface or playing media content. You can also check Vadim Makeev’s article on “When Is A Button Not A Button?”.
Accessible Disabled Buttons
It has become quite common for lengthy web forms to keep the “Continue” button disabled until the customer has provided all data correctly. This behavior acts as an indicator that something is wrong with the form, and it can’t be completed without reviewing the input. This works if the inline validation for every input field is working well, and it doesn’t work at all when it’s glitchy or buggy.
In “Disabled Buttons Suck”, Hampus Sethfors highlights the downsides of disabled buttons. With them in place, we do communicate that something is wrong, but we don’t really explain what is wrong, or how to fix it. So if the customer has overlooked an error message — be it in a lengthy form on desktop, or even in a short form on mobile, they’ll be lost. In many ways, keeping buttons active and communicating errors is more efficient.
And if it’s not possible, at least provide a way out with a button “I can’t complete the form, please help”, so customer support can get back to customers in case they get into trouble. If you need a more detailed refresher on web forms, “Form Design From One to Zero” will keep you busy.
In her article on CSS-Tricks, Sandrina Pereira explores the issue that the common way of using <button disabled> prevents not only the click but also the focus. While this might seem harmless, it causes confusion for screen reader users. Her suggestion: Swapping disabled with aria-disabled makes the experience more enjoyable as the button is still accessible by focus and it can trigger a tooltip, too — although marked disabled.
Cards offer a lot of advantages. They work well on mobile, provide large click areas, and the fact that they can be stacked both horizontally and vertically makes a lot of layout decisions easier. However, there’s no accessibility standard to follow, no <card> element or an ARIA design pattern. Instead, the potential accessibility barriers you might encounter depend on the card’s purpose and content. In his collection of inclusive components, Heydon Pickering looks into a few permutations of a simple card component and how to keep the balance between sound HTML structure and ergonomic interaction.
Adrian Roselli also wrote a great article that tackles an aspect of cards that can easily turn into their main accessibility pitfall: large click areas. They can make for extremely verbose controls when a user uses a screen reader to navigate them; for voice users, it can be confusing what to say to select the call to action. Adrian demonstrates how a little planning can solve this issue.
Another deep-dive into accessible card components comes from the team at Nomensa: In their blog post, they take a look at common issues around cards and block links and share valuable tips for making your cards more accessible — by re-ordering content to improve semantics, for example.
Accessible Carousels and Content Sliders
An accessible carousel sounds a bit like oxymoron — while there are plenty of scripts that provide the functionality, only few of them are accessible. Now there are, of course, accessible range sliders, but carousels are a slightly different component. As Alison Walden notices in her article on “If you must use a carousel, make it accessible”, the sighted person is not forced to use the carousel at all, but keyboard users are forced to navigate through the carousel in its entirety. At the very least, a hidden “skip” link could appear on keyboard focus. Also, once the person has tabbed through all the panel sets, focus should move to the next interactive element that follows the carousel.
Heydon Pickering suggests to use list markup to group the slides together, include previous and next buttons, snap points, and use invisible linked items removed from focus. The article also provides a code sample which uses IntersectionObserver, so you might need a polyfill for it.

Accessible Close Buttons
“Close” buttons are everywhere — in modals, ads, confirmation messages, cookie prompts and any overlays that will appear in your interface. Unfortunately, the functionality is often limited to mouse users, leaving screen reader users and keyboard-users out. We can fix it.
