Configure whether a class name can be added？

[ghost]

The problem

I want to add a class name to switch the background color, because the background color should also be able to switch between day and night modes

Implementation

Options Add claasName optional attributes

An option to automatically switch between dark and light background colors according to prefers-color-scheme would be great.

A trick I use with my Docusaurus documentation:

:root {
  --plugin-image-zoom-background-color: #fff;
}

[data-theme='dark'] {
  --plugin-image-zoom-background-color: #1e2125;
}

imageZoom: {
  options: {
    background: "var(--plugin-image-zoom-background-color)",
  },
},
