Reproduction URL

A Tailwind Play link or public GitHub repo that includes a minimal reproduction of the bug. Please do not link to your actual project, what we need instead is a minimal reproduction in a fresh project without any unnecessary code. This means it doesn't matter if your real project is private/confidential, since we want a link to a separate, isolated reproduction anyways.

A reproduction is required when filing an issue — any issue opened without a reproduction will be closed and you'll be asked to create a new issue that includes a reproduction. We're a small team and we can't keep up with the volume of issues we receive if we need to reproduce each issue from scratch ourselves.

The param addBase api of plugin functions does not work with html.dark but work with html#dark

the code is like:

plugins: [
    plugin(function ({ addBase }) {
      addBase({
        'html.dark': {
          background: 'black'
        }
      })
    })
  ]

Hey! This works as expected for me, as long as the dark class is present in one of your templates somewhere to make sure Tailwind knows the rule needs to be generated:

If you still have issues here please open a new issue that includes a proper reproduction as per the issue template and we can take a closer look 👍
