The fr unit

The fr unit represents a fraction of the available space in the grid container.

When to use it?

The main difference between the Flexbox and Grid layout is that Flexbox creates content-first design while Grid creates layout-first design.

If you are well aware of your content before making the layout, then the better option will be to use Flexbox, otherwise opt for the Grid.

Flexbox layout is the most appropriate for the components and small-scale layouts.

Grid layout is more focused to larger scale layouts which aren’t linear in their design.
