Like the flexbox, the grid is a layout module that allows you to align elements on a page. The crucial difference between flexbox and grid is that flexbox structures the layout in only one dimension — either a row or a column. The ideal use case for the flexbox is having several items that you want to space out evenly in a container either horizontally or vertically.

When you use the grid layout, you first create a layout and then put items into rows and columns. In other words, the grid properties work to help web designers create a high-level structure of a page.

Like the flexbox, the display:grid; declaration consists of a parent element and its child elements.
