janus winforms gridex删除了groupheader的上填充物
任何人都知道小组实际文本上方是否有空线或一般填充，还是只是填充，无论如何，是否有可能摆脱它，以便我实际上可以正确地居中我的内容？
<div class="flex h-screen w-screen items-center justify-center"> <div class="relative w-1/2"> <textarea class="h-52 w-full rounded-md border-2 border-gray-500 py-2 outline-none focus:border-blue-400 px-3"></textarea> <label class="text-md absolute top-0 left-3 -mx-1 -translate-y-1/2 bg-white px-1"> Comment </label> </div> </div>
功能应用程序（）{ 返回 （ <> function App() { return ( <> <div style={{ width: "100vw", height: "100vh", display: "flex", alignItems: "center", justifyContent: "center", backgroundColor: "black", }} > <Logo3 /> </div> </> ); } 应用程序与上述一样简单。背景应该是黑色的，但有时有一个初始的白屏，在加载应用程序之前出现了一秒钟。如何预防这个白屏？ 因此，最简单的方法是为您的HTML文件内的页面主体设置背景颜色。这样，有初始的背景颜色，当（重新）加载网站时，您将不会体验到Flash。 <style> body { background-color: black; } </style> 另一个更复杂的解决方案是使用服务器端渲染。 这个想法是让服务器提供DOM的初始版本。 加载和评估所有JavaScript代码后，该DOM将被React扩散和更改。 看一下 ReactDOMServer.renderToString(reactElement) 和ReactDOM.hydrate() 如果您正在使用节点backend。 我认为below是一种更干净的方式，只需转到您的index.html文件或您的React应用程序所使用的任何内容，然后在初始<html .. />tag中添加样式标签 取代＃111与您喜欢的深色。 e.g. <html lang="en" style="background-color: #111"> 随着您的应用程序样式的加载，这将被覆盖。
