theme.css 必须至少包含一条规则

Error message

theme.css 必须至少包含一条规则

What it means

Thrown by parse_safe_css at the end of parsing when no rule was successfully collected — the entire theme.css produced an empty parsed list even though it passed the earlier non-empty byte check (e.g. it contained only garbage that never formed a rule). The offending input is the overall theme.css content; the package is rejected because a skin must define at least one style rule.
