@haer0248: 我偷翻了一下，好像是因為這行 `background-color:#0000;` 導致的 往上翻在 ``` @layer base { ... button, input, select, optgroup, textarea { font:inherit; font-feature-settings:inherit; font-variation-settings:inherit; letter-spacing:inherit; color:inherit; opacity:1; background-color:#0000; border-radius:0 } ... } ```
