22 CSS Checkout Forms
This collection is dedicated to creating complex and adaptive checkout forms, where CSS Grid provides a robust, multi-column structure, and clever CSS techniques handle dynamic, JS-free logic. The examples showcase how layouts elegantly transform from desktop to mobile, while the :focus-within pseudo-class highlights entire sections to improve navigation. The core interactive technique involves using hidden radio inputs and the :checked pseudo-class for conditional logic, such as showing different fields based on the selected payment method. The result is an intuitive and fully interactive checkout interface built exclusively on the power of modern CSS.

Checkout Radios
A modern checkout form component utilizing the powerful CSS :has() selector to style parent containers based on the state of nested radio inputs.
UI Credit Card Checkout
This payment UI is a showcase of clean SCSS architecture, utilizing variables and a custom @mixin for maintainability. A key feature is its clever, JS-free state management for card selection, where input[type="button"] elements are toggled using the :focus pseudo-class to remove a grayscale() filter. The component’s cohesive design is further enhanced by custom-styled native <select> elements, achieved by stripping default browser styles with appearance: none;.
Credit Card Checkout
This payment UI demonstrates a classic front-end architecture, using CSS Flexbox to create a responsive two-column layout that gracefully stacks on smaller screens. All interactive functionality, including the custom card selection dropdown, is orchestrated by a concise vanilla JavaScript module that toggles a simple .visible class for state changes.
Credit Card Checkout
This JS-free form component achieves a distinct “neo-brutalist” aesthetic by pairing a solid border with a hard, offset box-shadow, creating a tactile, pseudo-3D effect. This visual system is applied to a modern Flexbox layout and is enhanced by polished micro-interactions, including a unique box-shadow outline on :hover and a clear background change on :focus for a cohesive user experience.
