A responsive CSS grid is a powerful tool for creating flexible and adaptive web layouts. It allows developers to design web pages that adjust seamlessly to different screen sizes and devices without relying heavily on media queries.

To start building a responsive grid, you need to define a grid container and its items. The grid container is the parent element that holds the grid items, and it is defined using the display: grid; property. Here is a basic example:

In this example, the grid-template-columns property uses the repeat() function to create columns that automatically fit the available space. The minmax() function sets the minimum and maximum size for the columns, ensuring they are at least 240px wide but can expand to fill the remaining space².
