grid-template-areas

grid-template-areas is a property in CSS that defines a grid layout by specifying the position and size of grid items based on named grid areas. It allows you to create a grid layout using a combination of rows and columns, and then assign specific HTML elements to specific areas within that grid layout.

The grid-template-areas property works by using a grid area name for each cell in the grid. These names are defined by enclosing them in quotes and separating them with spaces. For example:

grid-template-areas:
  "header header header"
  "nav    main   main"
  "nav    footer footer";

This defines a grid layout with three rows and three columns. The first row contains three cells with the name "header", the second row contains two cells with the names "nav" and "main", and the third row contains two cells with the names "nav" and "footer".

Once the grid areas are defined, you can assign specific HTML elements to those areas using the grid-area property. For example:

.header {
  grid-area: header;
}

.nav {
  grid-area: nav;
}

.main {
  grid-area: main;
}

.footer {
  grid-area: footer;
}

This will position the HTML elements with the class "header", "nav", "main", and "footer" in the corresponding grid areas defined in the grid-template-areas property.
