# Example app with styled-components
This example features how you use a different styling solution than [styled-jsx](https://github.com/zeit/styled-jsx) that also supports universal styles. That means we can serve the required styles for the first render within the HTML and then load the rest in the client. In this case we are using [styled-components](https://github.com/styled-components/styled-components).
For this purpose we are extending the `<Document />` and injecting the server side rendered styles into the `<head>`, and also adding the `babel-plugin-styled-components` (which is required for server side rendering). Additionally we set up a global [theme](https://www.styled-components.com/docs/advanced#theming) for styled-components using NextJS custom [`<App>`](https://nextjs.org/docs/advanced-features/custom-app) component.
## Deploy your own
Deploy the example using [Vercel](https://vercel.com):
Fix deploy buttons URLs (#20834) Fix all deploy button URLs in the Next.js repo to follow the following format: ``` https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/<EXAMPLE_NAME>&project-name=<EXAMPLE_NAME>&repository-name=<EXAMPLE_NAME> ``` The detailed docs for the Deploy Button can be found here: https://vercel.com/docs/more/deploy-button. Also updates legacy Vercel import flow URLs (starting with vercel.com/import or with vercel.com/new/project), to use the new vercel.com/new URLs. --- For example, for the `hello-world` example: The URL is https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/hello-world&project-name=hello-world&repository-name=hello-world And the deploy button looks like this: [![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/hello-world&project-name=hello-world&repository-name=hello-world) --- For reference, I used the following regexes to search for the incorrect URLs ``` \(https://vercel.com/import/git\?s=https://github.com/vercel/next.js/tree/canary/examples/(.*)\) \(https://vercel.com/import/git\?c=1&s=https://github.com/vercel/next.js/tree/canary/examples/([^&]*)(.*)\) \(https://vercel.com/import/project\?template=https://github.com/vercel/next.js/tree/canary/examples/(.*)\) https://vercel.com/import/git https://vercel.com/import/select-scope https://vercel.com/import https://vercel.com/new/project ```

### Try it on CodeSandbox
[Open this example on CodeSandbox](https://codesandbox.io/s/github/vercel/next.js/tree/canary/examples/with-styled-components)
### Notes
When wrapping a [Link](https://nextjs.org/docs/api-reference/next/link) from `next/link` within a styled-component, the [as](https://styled-components.com/docs/api#as-polymorphic-prop) prop provided by `styled` will collide with the Link's `as` prop and cause styled-components to throw an `Invalid tag` error. To avoid this, you can either use the recommended [forwardedAs](https://styled-components.com/docs/api#forwardedas-prop) prop from styled-components or use a different named prop to pass to a `styled` Link.
