What is CSS Grid Layout?

CSS Grid is a framework that offers a lot more freedom for developers than HTML. It allows developers to construct custom grids with more flexibility and control than ever before. In contrast to the block system, it has no layout restrictions and allows one to play around with UI elements up to one’s liking. It can also be used to position and size each element inside the grid using just CSS, and without affecting any HTML changes.

The image below shows the layout of the grid model.

 Important Terminology

Grid Item 

The grid container contains the grid items. 

Grid Line

The grid line is either a vertical or horizontal grid line that makes up the structure of the grid. 

Grid Cell

The smallest unit on a grid is referred to as a Grid cell. It is the space between the two adjacent rows and columns.

Rows

The grid row is the horizontal track of the grid.

Columns

The grid column is the vertical track of the grid.

Gutter

A gutter is a space between the rows and columns in the grid.

Grid Container

A Grid container is an element on which the display: grid property is applied. It is the direct parent of all the grid items. The items of the grid container are placed inside rows and columns.

Let’s understand the grid container better with the help of an example.

• grid-template-columns: It is used to set the size of the columns.
• grid-template-rows: It is used to set the size of the rows.
• grid-gap: The grid-gap property sets the gap between rows and columns.
• The fr unit is used to create flexible grid tracks. It represents a fraction of the available space in the grid container.

Repeating Grid Tracks

The repeating grid track is specified using the repeat() function. The function is useful when you have grid items of equal sizes.

The first argument represents the number of times the track should repeat, and the second item mentions the size of the track.

Align-Content and Justify-Content Property

The align-content is used to align the grid along the row-axis and justify-content is used to align the grid along the column axis.
