Websites compliant with digital accessibility regulations.

This principle assumes that a website or application can be used through the senses available to a given user. It can be achieved, for example, by providing transcripts for the hearing impaired or alternative text for images for the visually impaired.

According to the principle of operability, users should be able to use a website or application regardless of the device they are using. Navigation should be possible using only a mouse, only a keyboard, or a touchscreen.

To meet the principle of understandability, focus on maintaining a consistent look across your website or application. All buttons and navigation menus should appear the same or very similar on every page and be clearly labeled.

Compatibility, sometimes referred to as the principle of robustness, focuses on using proper industry standards, such as code compliant with HTML standards. It ensures that a website or application can be used regardless of the device being used (computer, phone, tablet, or screen reader for the visually impaired).
