What is a characteristic feature of the CSS Grid layout model?

The characteristic feature of the CSS Grid layout model is that it organizes content into a two-dimensional grid. This means that it allows developers to create layouts that can handle both rows and columns simultaneously, which provides a high level of control and flexibility when arranging elements on a webpage. The ability to define specific areas of the grid for placing content enables designers to create complex layouts that are responsive and can adapt to different screen sizes.

The other options do not accurately reflect the CSS Grid's capabilities. For example, while the grid does allow for flexible arrangements of rows, that is only part of its functionality; its two-dimensional aspect is what sets it apart. The notion that it does not allow overlapping elements is also incorrect, as CSS Grid can be designed to allow elements to overlap if desired. Finally, the statement about applying styles only to inline elements is misleading; CSS Grid can style block elements and inline-block elements, not limiting itself to inline styles exclusively.
