#div losing style

Based on the information provided in the extracts, there are several issues reported by users that involve styles not being loaded or disappearing in the production environment when using Next.js. This could be due to a variety of reasons, such as the way styles are loaded, the order in which they are defined, or even due to certain configurations in the production environment.
For instance, in issue #28340 (https://github.com/vercel/next.js/issues/28340), the user reported that some component styles are not loaded in development mode. The user was using component-level Sass via CSS Modules for styling.
In issue #46197 (https://github.com/vercel/next.js/issues/46197), it was reported that Tailwind styles disappear for a couple of seconds on HMR in the app directory.
In issue #13092 (https://github.com/vercel/next.js/issues/13092), the user reported that CSS Modules styles are defined in the wrong order in development mode, causing inconsistencies across environments.
In issue #22819 (https://github.com/vercel/next.js/issues/22819), the user reported that when using the Antd example, the website loads the CSS a second later in production mode, causing a visible transition from unstyled to styled components.
In issue #55246 (https://github.com/vercel/next.js/issues/55246), it was reported that Next.js on Vercel was transforming CSS to invalid syntax in production mode.
These issues suggest that the problem you're experiencing could be due to a variety of factors. It could be helpful to check if any of these scenarios apply to your case. If none of these seem to apply, it might be necessary to provide more specific details about your setup and the issue you're experiencing for a more accurate diagnosis.

Let me check the knowledge base for you. One moment! :books:
Based on the information provided in the extracts, there are a few issues reported by users that involve the use of styled-components and Antd in Next.js.
In issue #22819 (https://github.com/vercel/next.js/issues/22819), a user reported an issue with Antd where the CSS loads a second later in production mode, causing a visible transition from unstyled to styled components. This could potentially be related to your issue if you're noticing a delay in styles being applied.
In issue #57584 (https://github.com/vercel/next.js/issues/57584), a user reported an issue with styled-components in Next.js 14.0.0 where the Flash of Unstyled Content (FOUC) appears. This could be related to your issue if you're using Next.js 14.0.0 and are noticing a flash of unstyled content.
Without more specific details about your setup and the issue you're experiencing, it's hard to provide a more accurate diagnosis. However, these issues suggest that there could be a problem with how styled-components or Antd are being used or configured in your project. It might be helpful to check if any of these scenarios apply to your case.

@feral plaza Ok, I'll give it a read, another question. Should I create a document.tsx? I don't have my project
feral plazaBOT
Let me check the knowledge base for you. One moment! :books:
Yes, creating a _document.tsx file in your project can be beneficial for certain use cases. According to the Next.js documentation (https://nextjs.org/docs/pages/building-your-application/routing/custom-document), a custom Document can update the <html> and <body> tags used to render a Page.
Here's an example of how you can create a _document.tsx file:
import { Html, Head, Main, NextScript } from 'next/document'
export default function Document() {
return (
<Html lang="en">
<Head />
<body>
<Main />
<NextScript />
</body>
</Html>
)
}
However, it's important to note that _document is only rendered on the server, so event handlers like onClick cannot be used in this file. Also, <Html>, <Head />, <Main /> and <NextScript /> are required for the page to be properly rendered.
If you're using styled-components, you might need to customize the renderPage function in _document.tsx to support server-side rendering of styles. However, this is considered advanced and is not recommended unless necessary. Instead, consider incrementally adopting the App Router, which allows you to more easily fetch data for pages and layouts.
Remember, although you can use both routers in the same project, routes in app will be prioritized over pages. It's recommended to use only one router in your new project to avoid confusion.

@feral plaza but should I create it in an app? because I don't have a pages folder in my next
feral plazaBOT
Let me check the knowledge base for you. One moment! :books:
If you're using the App Router instead of the Pages Router in your Next.js project, you would typically create a layout.tsx file in the app/ directory at the root of your project, instead of creating _document.tsx, _app.tsx, and index.tsx in a pages/ directory.
However, if you have an existing _app or _document file, you can copy the contents (e.g. global styles) to the root layout (app/layout.tsx). Styles in app/layout.tsx will not apply to pages/*. You should keep _app/_document while migrating to prevent your pages/* routes from breaking. Once fully migrated, you can then safely delete them. If you are using any React Context providers, they will need to be moved to a Client Component (https://nextjs.org/docs/app/building-your-application/rendering/client-components) (source (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration)).
Remember, although you can use both routers in the same project, routes in app will be prioritized over pages. It's recommended to use only one router in your new project to avoid confusion (source (https://nextjs.org/docs/getting-started/installation)).

@feral plaza I don't understand, I already have a layout.tsx in app/ so I don't need a _document.tsx?

Let me check the knowledge base for you. One moment! :books:
Correct, if you're using the App Router and have a layout.tsx file in your app/ directory, you typically don't need a _document.tsx file.
The layout.tsx file in the app/ directory serves a similar purpose to _document.tsx and _app.tsx in the pages/ directory. It defines the root layout that applies to all routes inside app. This includes defining the <html> and <body> tags, which Next.js does not automatically create (source (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration)).
However, if you have an existing _app or _document file, you can copy the contents (e.g. global styles) to the root layout (app/layout.tsx). You should keep _app/_document while migrating to prevent your pages/* routes from breaking. Once fully migrated, you can then safely delete them (source (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration)).
So, in summary, if you're using the App Router and have a layout.tsx file, you typically don't need a _document.tsx file.

@feral plaza How to do this here using layout.tsx? import { promises as fs } from 'fs'
import * as path from 'path'
import Document from 'next/document'
class MyDocument extends Document {
static async getInitialProps(ctx) {
const initialProps = await Document.getInitialProps(ctx)
const css = await fs.readFile(
path.resolve('./node_modules/antd/dist/antd.min.css'),
'utf-8'
)
return {
...initialProps,
styles: (
<>
{initialProps.styles}
<style dangerouslySetInnerHTML={{ __html: css }} />
</>
),
}
}
}
export default MyDocument
