The CSS position property, especially the absolute value combined with top, left, right, bottom, and transform, lets you place text precisely on top of an image outside the page's normal document flow. Centering text over an image combines position: absolute with top: 50% and left: 50%, then transform: translate(-50%, -50%) keeps it centered regardless of its dimensions.

Developers import a module, such as Card.module.css, as a JavaScript object, gaining local scope, easier maintainability, reusable styles, and improved CSS specificity in React applications.
