Grid Layout is a CSS layout system that allows you to create complex, multi-dimensional grid structures for your web pages. It provides a way to define rows and columns in a grid, and then place content within those cells.

Here are the basic steps to create a grid layout using CSS Grid:

Define a Grid Container: To create a grid layout, you first need to define a container element and set its display property to “grid”. For example:

Define Rows and Columns: Next, you need to define the rows and columns of the grid using the “grid-template-rows” and “grid-template-columns” properties. For example:

This creates a grid with two rows (100px and 200px) and two columns (1fr and 2fr).

Place Content: Finally, you can place content within the cells of the grid using the “grid-row” and “grid-column” properties. For example:

This places the “item” element in the second column of the first row.

CSS Grid also provides many other features for creating complex layouts, such as grid gaps, grid lines, and grid areas. By using these features, you can create flexible, responsive, and visually interesting web layouts.
