This element is based on Quasar's `QBtn <https://quasar.dev/vue-components/button>`_ component.

The ``color`` parameter accepts a Quasar color, a Tailwind color, or a CSS color.

If a Quasar color is used, the button will be styled according to the Quasar theme including the color of the text.

Note that there are colors like "red" being both a Quasar color and a CSS color.

In such cases the Quasar color will be used.
