We’ll soon be able to use the inert attribute to remove, and then restore the ability of interactive elements to be discovered and focused. Ideally, we’d use something as simple as the dialog element in HTML, but unfortunately, it has massive accessibility issues. In all these cases, building an accessible modal will turn out to become quite an adventure, also known as a focus trap.Īs Eric Bailey explains in detail, you’ll need to identify the bounds of the trapped content, including the first and last focusable item, then remove everything that isn’t within it, move focus into the trapped content, listen for events that escape the boundary, restore the previous state and move focus back to the interactive element that triggered the trapped content. You might have a simple modal or overlay on the page, perhaps to confirm the customer’s input, or to show a couple of photos in a gallery, or just to confirm the user’s preferences.

Our sincere hope is that they will help you improve the accessibility and usability of your products, so next time you have to find a solution, it will be less daunting and more straightforward than before you opened this very newsletter.Īnd if you are looking for a deeper dive into psychology and usability, we have some online workshops on UX & front-end that you, or your wonderful colleagues, may find useful as well. In this issue, we’ve collected a couple of useful libraries and case studies to get accessibility just right: from accessible modals, tabs, and autocomplete to keyboard navigation and accessible icon links. And then, for every component we are building, we need to ensure that we keep them accessible over time. We have to keep in mind how our sites and applications work with a keyboard alone, whether navigation landmarks are properly assigned, how updates are announced by a screen reader, and whether we avoid any inaccessible libraries or third-party scripts. Building accessible pages and applications isn’t easy.
