Question

我正在尝试使用React和Material UI构建一个模拟网站，我使用RaisdedButtonExampleSimple组件来显示Material UI中的按钮。这是一个名为App-Intro的div，上面是带有文本的Div“Customer-Choice”。文本出现在按钮上方，即使它位于App.js代码中按钮下方的Div中。有这样的原因吗？

Picture of the display

.App {
    text-align: center;
}

.iconmenu {
    margin: auto;
}

.App-logo {
    /* animation: App-logo-spin infinite 20s linear; */
    height: 200px;
}

.App-header {
    background-color: rgb(255, 255, 255);
    height: 150px;
    padding: 20px;
    color: white;
}

.App-title {
    font-size: 1.5em;
}

.App-intro {
    font-size: 1.5em;
}

.Customer-Choice {}

@keyframes App-logo-spin {
    from {
        transform: rotate(0deg);
    }
    to {
        transform: rotate(360deg);
    }
}

import "./button.css";

import BadgeExampleSimple from "./badge";
import IconMenuExampleSimple from "./iconmenu.js";
import RefreshIndicatorExampleLoading from "./refreshindicator.js"
import RaisedButtonExampleSimple from "./button.js"


class App extends Component {
  render() {
    return (
      <MuiThemeProvider>
      <div className="App">
    <AppBarExampleIcon iconClassNameLeft={BadgeExampleSimple}
color1 = {lightGreen600} />
{/* <div className = "iconmenu"> <IconMenuExampleSimple/> </div> */}


  
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <div className="button1"><RaisedButtonExampleSimple/></div>
          <h1 className="App-title">Welcome to React</h1>
        </header>
        <h1 className="App-intro">
          Lawn Service and Home Cleaning Done Right
        </h1>
      </div>
      <div className="Customer-Choice">
      
      <h1>Why Customers Choose Us</h1>
      </div>
    </MuiThemeProvider>
    );
  }
}

export default App;

Answer 1

检查ErrorDocument 404 /error_pages/new404.html，它可能继承了导致问题的CSS。

您还可以为此<h1>Why Customers Choose Us</h1>添加一个类名，并将其作为

目标添加到CSS中

<h1 className="customerChoice">。
