Adding <meta name="viewport" ...>
in pages/_document.js
will lead to unexpected results since it cannot be deduped.
The viewport tag should be handled by next/head
in pages/_app.js
.
Set your viewport meta
tag in pages/_app.js
instead:
// pages/_app.js
import Head from 'next/head'
function MyApp({ Component, pageProps }) {
return (
<>
<Head>
<meta name="viewport" content="viewport-fit=cover" />
</Head>
<Component {...pageProps} />
</>
)
}
export default MyApp
- Issue #13230, which led to the creation of this warning.
