Ensuring interface components and navigation are functional.
The Operable principle focuses on the "Touch" of digital accessibility. It dictates that users must be able to use the interface across all input methods—keyboard, mouse, touch-screen, or voice. If a user can perceive your content but cannot interact with it, the web remains a closed door.
Make all functionality available from a keyboard. Many users with motor disabilities and all screen reader users rely on keyboard navigation to "touch" and interact with your site.
Primary Implementation: Ensuring all interactive elements (links, buttons, forms) can be reached and activated using the Tab and Enter keys.
Understand Keyboard Access StandardsProvide users enough time to read and use content. Automatic timeouts or moving content can prevent users from completing actions.
Primary Implementation: Providing ways to pause, stop, or hide moving content (like carousels) and allowing users to extend session timeouts.
Review Timing & Interaction GuidelinesDo not design content in a way that is known to cause seizures or physical reactions. High-frequency flashing is a primary barrier to safety.
Primary Implementation: Eliminating content that flashes more than three times in any one second period.
Examine Flashing & Safety StandardsProvide ways to help users navigate, find content, and determine where they are. This guideline covers the "road signs" of your digital product.
Primary Implementation: Using descriptive page titles, visible focus indicators, and "skip to content" links.
Master Navigable Wayfinding TechniquesMake it easier for users to operate functionality through various inputs beyond keyboard, including touch gestures and pointer interactions.
Primary Implementation: Ensuring target sizes are large enough to be easily tapped (at least 24x24 or 44x44 pixels) and avoiding reliance on complex gestures.
Review Input & Touch StandardsThe simplest way to test for Operability is to put your mouse aside and try to use your website with only your keyboard. Can you see where you are? Can you open every menu? Can you submit every form? If you get "trapped" anywhere, your site isn't yet Operable.
