Each container has a flex-start and flex-end points as shown on this diagram. While the list of items is provided in a linear way, Flex requires you to be mindful of rows and columns. For this reason, it has two coordinate axis.

The horizontal axis is referred to as Main-Axis and the vertical is the Cross-Axis. To control the behavior of content's width and gaps between that stretch horizontally across the Main-Axis you will use justify properties.

To control vertical behavior of items you will use align properties. If you have 3 columns and 6 items, a second row will be automatically created by Flex to accommodate for the remaining items.

Flex items equally distributed on the Main-Axis. This is the default view. We'll take a look at the properties and values to accomplish this in just a moment. How the rows and columns are distributed inside the parent element is determined by CSS Flex properties flex-direction , flex-wrap and a few others that will be demonstrated throughout the rest of this flex tutorial.

Here we have an arbitrary n-number of items positioned within a container. By default, items stretch from left to right. However, the origin point can be reversed. The default is row, which means flowing from left to right, as you would expect! When we change flex direction to column, the flex-flow property behaves in exactly the same way as in previous examples. Except this time, they follow the vertical direction of a column.
