Code Walkthrough and Explanation

`justify-items`

justify-items is a CSS property that is used to align grid items along the horizontal axis (i.e., along the columns) when there is extra space available within a grid cell. It applies to all grid items within a container and can be used to override the justify-items value set on the container.

The justify-items property accepts the following values:

start: This is the default value, which aligns grid items to the left edge of the grid cell.
end: This value aligns grid items to the right edge of the grid cell.
center: This value centers grid items within the grid cell.
stretch: This value stretches grid items to fill the entire width of the grid cell.
baseline: This value aligns grid items along the baseline of their content.

`justify-self`

justify-self is a CSS property that is used to align a grid item along the horizontal axis within its cell. It applies only to a single grid item and overrides the justify-items property set on the parent grid container.

The possible values for justify-self are:

start: aligns the grid item to the start of the cell.
end: aligns the grid item to the end of the cell.
center: aligns the grid item to the center of the cell.
stretch: stretches the grid item to fill the entire cell.
auto: the default value, which applies the value of the justify-items property set on the parent grid container.
