未知规则 @propertycss(unknownAtRules)

未知的规则

当我将鼠标悬停在@property上方时，它也有一条黄色下划线，并且该属性没有位置.

我阅读了一些文档，无法找出我的错误:

@property --rotate {
  syntax: "<angle>";
  inherits: false;
  initail-value: 132deg;
}
:root {
  --card-height: 65vh;
  --card-width: calc(var(--card-height));
}

body {
  min-height: 100vh;
  display: flex;
  align-items: center;
  flex-direction: column;
  padding-top: 2rem;
  padding-bottom: 2rem;

  justify-content: center;
}
