👉 The grid fluid is a CSS layout technique that enables designers to create flexible, responsive web layouts by defining areas within a grid system that can dynamically adjust their size and position based on the available space. It allows for precise control over how elements are distributed across different grid tracks, ensuring that content scales smoothly across various screen sizes. By using percentages or fractional units (like `fr`), grid fluid can adapt to the container's dimensions, providing a seamless user experience on desktops, tablets, and mobile devices. This approach enhances both the aesthetic appeal and functionality of web designs, making them more accessible and user-friendly.
