如何透過僅滿足此條件將樣式套用至 .apply-style-here 的父 div

1. .apply-style-here 的父級應該是普通 div 或沒有 .second-stage 類別
2. .apply-style-here 父級的父級不應該有 .second-stage 謝謝

嘗試解決辦法

/* Result: Put border to all parent of apply-style-here class */ .first-stage:has(div > .apply-style-here) > div { /* margin-top: 20px; */ border: 1px solid red; } /* Result: No styles applied at all */ .first-stage:not('div > .second-stage') > div { border: 1px solid blue; } /* Result: No styles applied at all */ .first-stage:has(div:not('.second-stage') > .apply-style-here) > div { border: 1px solid blue; } /* Result: Applied to all .apply-style-here even second .second-stage is present */ .first-stage:has(div:not(.second-stage) > .apply-style-here) > div { border: 1px solid blue; } /* Result: Applied to all .apply-style-here even second .second-stage is present */ .first-stage:has(div:not(.second-stage > .apply-style-here)) > div { border: 1px solid blue; }
