## Browser support
Drop-in is supported in all browsers supported by the [Braintree JavaScript Client SDK](http://braintree.github.io/braintree-web/current/#browser-support).
## Customization
The design of Drop-in is intentionally opinionated, and while we aimed to make the design work in many scenarios, the design of your website may conflict with the default design of Drop-in.
For minor UI customizations, [review our documentation](https://developer.paypal.com/braintree/docs/guides/drop-in/customization/javascript/v3#customize-your-ui).
For more substantial changes, you may [fork](https://help.github.com/articles/fork-a-repo/) Drop-in, make your desired changes and build the assets by running `npm run build`. By default, Drop-in uses a hosted version of the built stylesheet. To override this behavior and use a custom stylesheet instead, simply add `` tag to your page with the id `braintree-dropin-stylesheet`.
Drop-in uses the [Braintree JavaScript SDK](http://github.com/braintree/braintree-web). So if a fully customized UI is what you're looking for, Drop-in may be used as a reference implementation for using the JavaScript SDK.
## License
Drop-in is open source and available under the MIT license. See the [LICENSE](LICENSE) file for more info.
