使用createMuiTheme覆盖div，p和body的默认样式 [英] Using createMuiTheme to override default styles on div's, p's, body
问题描述
这可能是一个简单的材质UI主题自定义"问题.
This is perhaps a simple Material UI Theme Customization question.
我想做的是覆盖<body>上的默认样式(以及将来的其他常见标签).现在在我的React树的根目录:
What I want to do is to override the default styling on <body> (and other common tags in the future). Right now at the root of my React tree:
import theme from './mui-theme'
ReactDOM.render(
<Router>
<ThemeProvider theme={theme}>
<StylesProvider injectFirst>
{/* CssBaseline kickstart an elegant, consistent, and simple baseline to build upon. */}
<CssBaseline />
<App />
</StylesProvider>
</ThemeProvider>
</Router>,
document.getElementById('root'),
);
有一个主题，它指定了一些内容，但省略了'body1'
There's a theme that specifies some things but leaves out 'body1'
const theme = useTheme()和console.log(theme)显示它的定义为:
typography:
body1:
fontFamily: "Roboto,"Helvetica Neue""
fontSize: "1rem"
fontWeight: 400
lineHeight: 1.5
这是我想要的设置.但是，要使用该设置，我必须将Typography标记与variant='body1'一起使用.否则，div中的文本具有CssBaseline提供的样式.这是body标记上的规则:font-size: .875rem;，我想覆盖它.
This is the setting I want. However to use that setting I have to use the Typography tag with variant='body1'. Otherwise, text inside a div has styling provided by CssBaseline. That's the rule on the body tag: font-size: .875rem; which I wish to override.
人们是否通过使用createMuiTheme覆盖CssBaseline提供的样式?如果是这样，我添加:
Do people override styling provided by CssBaseline by using createMuiTheme? If so, I added:
body: {
fontSize: '1rem',
},
哪个出现在console.log(theme)上，但是如何告诉<body>标签实际使用该样式?
Which shows up on console.log(theme), but how tell the <body> tag to actually use that style?
推荐答案
以下是覆盖CssBaseline这方面的一个示例:
Here is an example of overriding this aspect of CssBaseline:
import PropTypes from "prop-types";
import { withStyles } from "@material-ui/core/styles";
const styles = theme => ({
"@global": {
body: {
...theme.typography.body1
}
}
});
function MyCssBaseline() {
return null;
}
MyCssBaseline.propTypes = {
classes: PropTypes.object.isRequired
};
export default withStyles(styles)(MyCssBaseline);
import React from "react";
import ReactDOM from "react-dom";
import CssBaseline from "@material-ui/core/CssBaseline";
import MyCssBaseline from "./MyCssBaseline";
function App() {
return (
<>
<CssBaseline />
<MyCssBaseline />
<span>
Here is some text in the body that is getting the body1 styling due to
MyCssBaseline.
</span>
</>
);
}
ReactDOM.render(<App />, document.querySelector("#root"));
