这里我想在桌面上隐藏一个按钮import React from 'react';
import Classes from './toolbar.css';
import Logo from '../../logo/logo.js';
import Navitems from '../navigation-items/navigation-items.js';
const toolbar = (props) => {
return (
<header className={Classes.Toolbar}>
<div className={Classes.SideDrawerVisibility}>
<button onClick={props.sideDrawerTogglerHandler}> Click Me </button>
</div>
<div className={Classes.Logo}>
<Logo height="100%"/>
</div>
<nav className={Classes.DesktopOnly}>
<Navitems />
</nav>
</header>
)
}
export default toolbar;
，即这行JSX
click me在我的Css中我做过类似的事情
<div className={Classes.SideDrawerVisibility}>
<button onClick={props.sideDrawerTogglerHandler}> Click Me </button>
</div>
但按钮仍然可见并且可以在桌面和移动设备上工作，对我可能做错了什么的想法？
答案 0 :(得分：0)
您无法导入css类选择器，例如import Classes from './toolbar.css';。
您必须将className prop的值设为字符串。
改变你的道具，
<div className="SideDrawerVisibility">
<button onClick={props.sideDrawerTogglerHandler}> Click Me </button>
</div>
并导入为，
import './toolbar.css';
你可以看到它有效。
