Drop-in is supported in all browsers supported by the Braintree JavaScript Client SDK.
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.
For more substantial changes, you may fork 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. 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.
Drop-in is open source and available under the MIT license. See the LICENSE file for more info.
