![]() ![]() Depending on the screen reader, it’s also announced slightly differently. It’s worth noting that aria-describedby is only meant to some HTML elements. “Your address, input Remember to include the door and apartment.” How Descriptions Are Announced For example, in the demo above, the Voice Over would announce. The aria-describedby is announced after the label with a slight pause between both. In short, we should use aria-label for critical information and aria-describedby for additional information. The attribute aria-labelledby is an alternative to and aria-label, responsible for the field’s accessible name. The Difference Between aria-labelledby And aria-describedby So, for now, we’ll need to stick with aria-describedby. Open the Pen Field Validations - aria-describedby by Sandrina Pereira.Īn ARIA attribute aria-description exists, but it’s not yet supported by most screen readers. Remember to include the door and apartment. With it, SR will read the description automatically when the user focuses on the field input. To do so, we can connect the description to the input by using the aria-describedby attribute, which accepts an id pointing to the description element. In the same way sighted users can see the description (assuming a color contrast that meets WCAG 1.4.3 Contrast Minimum), the SR users also need to be aware of it. The field label is the first visual instruction to know what to fill in, followed by a description when needed. Each one includes a Copeden demo and a video recording, which hopefully will give you a better idea of how screen readers behave in forms, field descriptions, and errors. Through the article, I’m using VoiceOver in macOS Catalina for all the scenarios. By using them, Assistive Technologies like screen readers will better describe a given element to the user. The reason is that we, developers, forget to implement those fields with screen readers in mind most of the time.Ĭurrently, many of the field validations can’t be solved with native HTML elements, so we are left with the last resource: ARIA attributes. Most prefer to Tab or use special shortcuts to quickly jump through the fields, but oftentimes can’t do it. However, this shouldn’t stop us from building the common solid foundations that are strongly supported by all.Ī while ago, I asked on Twitter how screen reader users navigate forms. For example, NVDA works better with Firefox, while VoiceOver works best with Safari, and both have slightly different behaviors. Similar to browsers, screen readers (SR) behave slightly differently from each other: different shortcuts, different semantic announcements, and different features support. For example, screen readers would read a field name to its user. This is mostly about setting a compliant focus indicator for each form control.Įach form field must have an accessible name (label), so people who use assistive technologies can identify each field. The form can be navigated using only the keyboard, so people who don’t use a mouse can still fill and submit the form. Table Of Contentsīefore we get into validation, let me recap the accessibility fundamentals in forms: ![]() With these two concepts clarified, we are now ready to dive into accessible validations. A visual representation of two circles (Accessibility and Usability) that intersect in the middle creating UX. Once overlapped will take ‘User Experience’ to its best. Usability is about how easy it is to use the website. Accessibility is about ensuring anyone can access the content. You can look at ‘Accessibility’ and ‘Usability’ as two equally important universes with their own responsibilities. That’s what I’ll explore through this guide. The other half is ensuring that any person knows the field is invalid and easily understands how to fix it. AccessibilityĬhoosing the best UX approach is just half of the challenge. ![]() There, you’ll learn about the different approaches to validate a field and what are the caveats and trade-offs of each one. To get a really good grasp of the challenges in this process, I highly recommend you to read the deep-dive “ Designing better inline validations UX” from Vitaly. For example, making the process of fixing an invalid field easier or writing better descriptions so the user can fill the field without facing an error message. Usability is about improving a given action until it’s as easy and delightful as possible. “What’s the difference between usability and accessibility?” you may ask. When it comes to form validation, we can explore it from two perspectives: usability and accessibility. In this guide, Sandrina breaks down what we need to take into consideration, so that nobody gets stuck on an inaccessible invalid field. Each time we build a field validation from scratch, accessibility doesn’t come out of the box. ![]()
