theme.css 规则数量超过限制

Error message

theme.css 规则数量超过限制

What it means

Thrown by parse_safe_css when the number of successfully parsed rule blocks exceeds 128. It fires after pushing each SafeCssRule, capping total rule count so compiled CSS output stays bounded. The offending input is the rule count of theme.css as a whole.
