React 样式中的 '& > *'
'& > *' in React's styles
我有以下代码:
const useStyles = makeStyles(theme => ({
row: {
'& > *': {
fontSize: 12,
fontWeight: 'bold',
color: 'rgba(33,34,34,0.5)',
letterSpacing: 0.5,
lineHeight: '16px',
},
},
}));
任何人都可以向我解释这行是什么意思:
'& > *': {
欣赏。
>
是 CSS
中的 child combinator
The >
combinator selects nodes that are direct children of the first element.
*
是 CSS 中的 universal selector。
Selects all elements. Optionally, it may be restricted to a specific namespace or to all namespaces.
&
是 SCSS
中的 a parent selector
In CSS-in-JS it may refer to the current component selector
The parent selector, &
, is a special selector invented by Sass that’s used in nested selectors to refer to the outer selector
由于 React-Material-UI 在其实现中使用了 JSS,所以这样的语法是可能的。
所以结合以上所有内容,& > *
意味着:对所有当前父级的直接子级的所有元素类型应用 CSS
