Diagnoses

Here is how rule engines diagnose the button name not visible issue for HTML element 54 of the Mozilla Foundation join us page.

1. The button content has only whitespaces. Having only defined an attribute aria-label="Toggle navigation" is not sufficient and it is recommended to have the content instead, e.g. at least visually hidden, but exposed to assisitve technologies. Some users are disabling styles for better readability, and also description from attribute is not available for automatic translators.

   Rule engine: ASLint (eSSENTIAL Accessibility)

   Rule: empty_button_description
