display:grid; grid-template-areas

Unfortunately, as an AI language model, I do not have the capability to display or execute code. However, I can provide some information on the CSS property "display: grid" and the related property "grid-template-areas".

"display: grid" is a CSS property that allows you to create a grid of rows and columns for positioning and aligning elements. It is a powerful tool for creating complex layouts, as it allows you to define the size and position of grid items in a more precise way than traditional layout methods.

"grid-template-areas" is a property that allows you to define named areas within the grid, which can then be used to position grid items. This property works by defining the grid as a series of rows and columns, and then assigning a name to each cell in the grid. Grid items can then be positioned within these named areas using the "grid-area" property.

Here is an example of how to use "grid-template-areas" in conjunction with "display: grid":

.container {
  display: grid;
  grid-template-areas:
    "header header header"
    "sidebar content content"
    "footer footer footer";
}

.header {
  grid-area: header;
}

.sidebar {
  grid-area: sidebar;
}

.content {
  grid-area: content;
}

.footer {
  grid-area: footer;
}

In this example, the grid is defined with three rows and three columns, and each cell is given a name using the "grid-template-areas" property. Grid items are then positioned within these named areas using the "grid-area" property.
