描述

The spec mentions the "footnote rule", but doesn't actually specify how to create it.

I tried to create a 20% wide rule with @footnote::before:

@page
   @footnote::before {
        display: block;
        width: 20%;
        border-top: solid 0.2mm;
    }
}

but the "::before" seems to be stripped and the rule applied to the entire area instead:

ss

Is it reasonable to expect "::before" to apply to the footnote area?

研究方向
Investigate how WeasyPrint handles CSS at rules like @footnote and pseudo elements. Check the CSS parser module (likely weasyprint/css/) for how @footnote::before is parsed. Refer to the CSS GCPM spec for footnote rule behavior. Look for existing tests for footnote rules and pseudo elements.
