The CSS Grid Layout Module is specifically designed for building two-dimensional layouts with rows and columns. This method allows developers to easily control the size, position, and alignment of items within the grid.

By setting 'display: grid;' on a container element, developers can then use properties such as 'grid-template-rows' and 'grid-template-columns' to define the structure of the grid. This functionality makes it straightforward to create complex layouts that adapt to varying screen sizes, enhancing responsiveness without the need for additional layout techniques.

The other choices involve methods that do not utilize the grid layout features. Using 'display: flex;' only applies to a flexible box layout, which is suitable for one-dimensional layouts, whether in a row or a column, but lacks the ability to design grids with both rows and columns. Incorporating JavaScript for layout manipulation can be useful in specific scenarios, but the fundamental creation of a grid layout does not require scripting—it can be achieved purely with CSS. Lastly, relying solely on CSS floats and clear properties is an older technique that does not offer the same capabilities or ease of use as CSS Grid, making
