Back to top button colors

[OriolAbril]

I noticed that the hover color for the "back to top" button is hardcoded to violet, so changing --pst-color-secondary results in strange/unexpected behaviour where the button goes from the custom color to violet on hover. I checked the behaviour when no colors are changed and I noticed the hover has a darkening effect between two shades of violet. I also noticed the --pst-color-secondary-highlight that is defined when using sphinx-design which would give nearly the same effect (and work for any --pst-secondary-color).

Would it be ok to include the ...-highlight colors as part of the theme and use that for the hover effect in "back to top" button?

Thanks for opening this issue, @OriolAbril. This was hardcoded while completing the design system work, and we forgot to revisit it.

I will update the button colour.

These should be included in the same way that --pst-color-xyz are included, for example if I inspect the PyData documentation I can see these in the developer tools

--pst-color-secondary-text: #14181e;
--pst-color-secondary-highlight: #6d13fc;
--sd-color-secondary-highlight: var(--pst-color-secondary-highlight);

so I am assuming you are asking for these to be customisable as described in https://pydata-sphinx-theme.readthedocs.io/en/stable/user_guide/styling.html ?

I will push a fix soon so this is doable
