:not()CSS伪类未按预期工作

sass css

Frankey · 技术社区 · 10 月前

一个简单的,为什么

:not(.theme) small{
  font-size: 40px;
}

:not(.theme *) small{
  text-decoration: underline;
}

*:not(.theme *) small{
  font-weight: bold;
}

正在对所有人生效 small html元素? 我的假设是,只有 小的 不是类父级的后代的元素 theme 受到影响。

同样适用于

:not(.theme *) .small-class{
  text-transform: capitalize;
}

影响所有小班元素。

body {
  background: #6e28d9;
  padding: 0 24px;
  color: white; /* Change my color to yellow */
  margin: 0;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: column;
  gap:20px;
}

.theme small {
  color: black;
}

:not(.theme) small{
  font-size: 40px;
}

:not(.theme *) small{
  text-decoration: underline;
}

*:not(.theme *) small{
  font-weight: bold;
}

small:not(.theme *){
  letter-spacing: 10px;
}

:not(.theme *) .small-class{
  text-transform: capitalize;
}
