Before Flexbox, we might have paired the preceding markup with the following CSS: This layout works, but it has one major drawback: it requires us to constrain the width of our images so that we know how much padding to use.

See the Set column-reverse and the start and end lines are again switched. Which of hte following is a shorthand property that configures both the placement and dimensions of items on the grid?

In practice, your projects will probably mix both of these techniques, as well as floats. The cross axis runs perpendicular to the main axis, therefore if your flex-direction (main axis) is set to row or row-reverse the cross axis runs down the columns. This will break the 3 column layout because the combined width of the columns exceed 100%. You might have a design, perhaps a card that will display a news item.
