Focus trapping keeps keyboard focus contained within a specific element, such as a modal. It prevents users from navigating out of the dialog by returning focus to the first element when tabbing out of the last element and vice versa. Creating focus traps enhances accessibility in web applications. Using utility functions, such as those from Splendid Labz, simplifies the process by detecting focusable elements and managing focus through keydown event listeners, making implementation easier.
Focus trapping is a method that ensures focus remains within a specified element, such as a modal. Tabbing beyond the last item returns focus to the first.
The value of focus trapping is evident in accessible modals, which helps ensure users can navigate with keyboard controls without leaving the modal context.
Implementing focus trapping can be complex due to the need to manage multiple focusable elements. The solution includes using codes that identify and trap focus effectively.
To make focus trapping easier, certain utility functions can be leveraged, like the ones from Splendid Labz, to detect focusable elements and manage focus with event listeners.
