-So far, we have focused on aligning items or an individual items inside the area defined by a {{glossary("flex_container")}} containing a single line of flex items. When flex items are allowed to wrap across multiple lines, the {{cssxref("align-content")}} property can be used to control the distribution of space between the lines, also known as **packing flex lines**.

 For `align-content` to have an effect, the cross axis dimension (the height in this case) of the flex container must be greater than needed to display the items. It then works on all the items as a set. The `align-content` values dictate what happens with the extra available space and the alignment of the entire set of items within it.

 To create a gap between flex items, use the {{cssxref("gap")}}, {{cssxref("column-gap")}}, and {{cssxref("row-gap")}} properties. The {{cssxref("column-gap")}} property creates gaps between items in a row. The {{cssxref("row-gap")}} property creates gaps between flex lines when you have {{cssxref("flex-wrap")}} set to `wrap`.
 
 The {{cssxref("gap")}} property is a shorthand that sets both `row-gap` and `column-gap`.
-The gap between flex items or between flex line depends on the direction. If the {{cssxref("flex-direction")}} property creates rows, the first value defines the gap between flex lines, and the second value defines the gap between items within each line. With columns (when `flex-direction` is set to `column` or `column-reverse`), the first value defines the gap between flex items, and the second value defines the gaps between flex lines.
