Diagnoses

Here is how tools diagnose the button name not visible issue for HTML element 932 of the Centre for Effective Altruism page.

1. The button should have a description, but the content is empty. Having only defined an attribute aria-label="Watch The why and how of effective altruism" 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.

   Tool: ASLint (eSSENTIAL Accessibility)

   Rule: empty_button_description
