我将react-universally用作样式的ReactJS应用样板和引导程序4。这里的主要成分是DemoApp：在ReactJS应用程序中加载全局引导配置

It's a pain to manage/generate them. I run both these in order,

<link
rel="stylesheet"

<link
rel="stylesheet"
href="/scripts/css/bootstrap.css"

</Helmet>
<Header />
<div style={{ paddingTop: '2rem', paddingBottom: '2rem' }}>
<Switch>
<Route exact path="/" component={AsyncHomeRoute} />
<Route path="/counter" component={AsyncCounterRoute} />
<Route path="/about" component={AsyncAboutRoute} />
<Route component={Error404} />

</div>
</div>
);
}
export default DemoApp;
而且我global.css文件，该样式的所有应用程序：
html {
box-sizing: border-box;
font-family: 'Tangerine', serif !important;
color: red;
}
*,
*:before,
*:after {
box-sizing: border-box;
margin: 0;
padding: 0;
}
/* Inline our ul for our menu */
ul {
margin: 0;
padding: 0;
list-style-type: none;
}
ul li { display: inline; margin: 0 .5rem; }
我的问题是，字体集（柑橘）没有被显示。它正在被应用，但之后被boostraps _reboot.css覆盖，将所有字体设置为引导默认值。
我可以想象这是由于加载引导程序之前正在执行的import "./globals.css"命令引起的，所以当我加载引导程序时，它调用_reboot来重置所有参数，包括其字体，覆盖我的设置。
如何使用DemoApp显示的组件方法反转该顺序并在引导程序完成其设置周期后加载globals.css，以便我的字体可以毫无问题地使用？
如果不可能，是否有其他解决方案可用于在ReactJS环境中全局设置引导程序变量？
感谢您的帮助。
您在这里忘记了一个空格：'serif！important;'它是'serif！important;' – dagatsoin
