w-{fraction} is not work in stylus @apply

[x-ray-s]

In Stylus if the input is

.block {
  @apply w-1/4;
}

The output will be

...
  @apply w-1 / 4;

The CSS syntax identifiers can contain only the characters [_-a-zA-Z0-9]，the / will be parsed as an arithmetic operator.
w-1 is ident, / is literal, so I got an error output.
Suggest supporting an alias, like w-1_4.

Hey! You'll have to use the @css directive to tell Stylus not to process it:

No plans to make changes to Tailwind itself to support specific preprocessors unfortunately, we really recommend just using PostCSS:
