Credit Addition Form - Copy this Html, Tailwind Component to your project

A form with a white and black theme, fully filling the screen's width and height. There will be a title called 'Add Credit' at the top, followed by a 'Client ID' text field, visible with a label next to it. Below that, there will be a text showing how many credits the client has. Underneath, there will be an input field for the desired credit amount. Finally, there will be an 'Add Credit' button. The UI should have a clean, attractive design.
