Fluid elements adapt gracefully, resizing in harmony with screen changes to maintain a balanced design. Commonly used in both responsive and fluid grids, they ensure the interface remains consistent across various device sizes.

When designing with fluid elements, it's essential to set minimum and maximum limits to prevent them from becoming too small to interact with or so large that they overpower the design. Consider using fluid elements for sections where scalability is key, such as adaptable content containers or interface components that should offer a seamless experience across multiple devices.
