theme.css 声明数量超过限制

Error message

theme.css 声明数量超过限制

What it means

Thrown by parse_safe_css when the total declaration count across all rules exceeds 512. It fires while iterating declarations (each property/value pair increments a counter), guarding against oversized stylesheets that would slow the Safe CSS compiler. The offending input is the aggregated declaration count of theme.css, not a single rule.
