Analysis of each value:

The order property sets the properties of the elastic child elements within the elastic container:
examples
.flex-item {
background-color: cornflowerblue;
width: 100px;
height: 100px;
margin: 10px;
}
.first {
-webkit-order: -1;
order: -1;
}

Set the "margin" value to "auto" value to automatically obtain the remaining space in the elastic container. Therefore, setting the vertical margin value to "auto" can make the elastic child element completely centered in both upper axis directions of the elastic container.
The following example sets margin-right: auto; on the first elastic child element. It places the remaining space to the right of the element:
examples
.flex-item {
background-color: cornflowerblue;
width: 75px;
height: 75px;
margin: 10px;
}
.flex-item:first-child {
margin-right: auto;
}
