+   `Sphinx Design buttons
+   <https://sphinx-design.readthedocs.io/en/latest/badges_buttons.html>`__
+   are actually links, meaning they are rendered in HTML with ``<a>`` tags
+   instead of ``<button>``. Use them if you need a link to look like a button,
+   however, be aware that they do not follow accessibility best practices for
+   native button components such as using the correct `ARIA attributes
+   <https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/button_role>`__.

 If in your site's `custom CSS file <custom-css>`_ you override the `CSS custom properties <css-variables>`_ ``--pst-color-*`` (where ``*`` is one of the semantic color names, such as ``primary``, ``danger``), badges and buttons will automatically use the custom color.
