The place-content CSS property sets how browsers distributes space between and around content items in a flexbox container. It's a shorthand for align-content and justify-content.

Syntax

/* Positional alignment */ 
/* align-content does not take left and right values */
place-content: center start;  
place-content: start center; 
place-content: end left; 
place-content: flex-start center;
place-content: flex-end center; 

/* Baseline alignment */ 
/* justify-content does not take baseline values */
place-content: baseline center; 
place-content: first baseline space-evenly; 
place-content: last baseline right;

/* Distributed alignment */
place-content: space-between space-evenly; 
place-content: space-around space-evenly;
place-content: space-evenly stretch; 
place-content: stretch space-evenly; 

/* Global values */
place-content: inherit;
place-content: initial;
place-content: unset;

The first value is the align-content property value, the second the justify-content one.

Important: If the second value is not present, the first value is used for both, provided it is a valid value for both. If it is invalid for one or the other, the whole value will be invalid.

Values

start
The items are packed flush to each other toward the start edge of the alignment container in the appropriate axis.
end
The items are packed flush to each other toward the end edge of the alignment container in the appropriate axis.
flex-start
The items are packed flush to each other toward the edge of the alignment container depending on the flex container's main-start or cross-start side.
This only applies to flex layout items. For items that are not children of a flex container, this value is treated like start.
flex-end
The items are packed flush to each other toward the edge of the alignment container depending on the flex container's main-end or cross-end side.
This only applies to flex layout items. For items that are not children of a flex container, this value is treated like end.
center
The items are packed flush to each other toward the center of the alignment container.
left
The items are packed flush to each other toward the left edge of the alignment container. If the property’s axis is not parallel with the inline axis, this value behaves like start.
right
The items are packed flush to each other toward the right edge of the alignment container in the appropriate axis. If the property’s axis is not parallel with the inline axis, this value behaves like start.
space-between
The items are evenly distributed within the alignment container. The spacing between each pair of adjacent items is the same. The first item is flush with the main-start edge, and the last item is flush with the main-end edge.
baseline
first baseline

last baseline
Specifies participation in first- or last-baseline alignment: aligns the alignment baseline of the box’s first or last baseline set with the corresponding baseline in the shared first or last baseline set of all the boxes in its baseline-sharing group.
The fallback alignment for first baseline is start, the one for last baseline is end.
space-around
The items are evenly distributed within the alignment container. The spacing between each pair of adjacent items is the same. The empty space before the first and after the last item equals half of the space between each pair of adjacent items.
space-evenly
The items are evenly distributed within the alignment container. The spacing between each pair of adjacent items, the main-start edge and the first item, and the main-end edge and the last item, are all exactly the same.
stretch
If the combined size of the items is less than the size of the alignment container, any auto-sized items have their size increased equally (not proportionally), while still respecting the constraints imposed by max-height/max-width (or equivalent functionality), so that the combined size exactly fills the alignment container

Formal syntax

<'align-content'> <'justify-content'>?

Example

CSS

#container {
  display: flex;
  height:240px;
  width: 240px;
  flex-wrap: wrap;
  background-color: #8c8c8c;
  writing-mode: horizontal-tb; /* Can be changed in the live sample */
  direction: ltr; /* Can be changed in the live sample */
  place-content: flex-end center; /* Can be changed in the live sample */
}

div > div {
  border: 2px solid #8c8c8c;
  width: 50px;
  background-color: #a0c8ff;
}

.small {
  font-size: 12px;
  height: 40px;
}

.large {
  font-size: 14px;
  height: 50px;
}

HTML

<div id="container">
  <div class="small">Lorem</div>
  <div class="small">Lorem<br/>ipsum</div>
  <div class="large">Lorem</div>
  <div class="large">Lorem<br/>impsum</div>
  <div class="large"></div>
  <div class="large"></div>
</div>
