How to properly implement accessibility for custom form controls, such as custom checkboxes and switches?
Creating custom form controls often requires developers to abandon standard tags like input in favor of styled div or span containers. However, this breaks standard accessibility because assistive technologies lose information about the element's purpose and state. To fix this, it is necessary to use correct ARIA roles and ensure full keyboard support.
First, the element must be assigned an appropriate role using the role attribute, such as checkbox or switch. This will allow screen readers to correctly identify the component when it receives focus. In addition, the state of the element needs to be dynamically updated using the aria-checked attribute, which can take values of true, false, or mixed.
It is equally important to provide keyboard navigation. The custom element must be included in the page focus sequence using the tabindex attribute with a value of
Finally, every custom control must have an associated text label. This can be done using the aria-label attribute containing a description of the function, or by linking the element to visible text on the screen via the aria-labelledby attribute. This approach ensures that users with visual or motor impairments can easily interact with interactive forms on the site.
