As you can see in the code below, the left div inside the flex container stretches to meet the height of the right div. Is there an attribute I can set to make its height the minimum required for holding its content (like usual height: auto
divs outside flex containers)?
#a {
display: flex;
}
#a > div {
background-color: red;
padding: 5px;
margin: 2px;
}
#b {
height: auto;
}
<div id="a">
<div id="b">left</div>
<div>right<br>right<br>right<br>right<br>right<br></div>
</div>
The align-items
, or respectively align-content
attribute controls this behaviour.
align-items
defines the items' positioning perpendicularly to flex-direction
.
The default flex-direction
is row
, therfore vertical placement can be controlled with align-items
.
There is also the align-self
attribute to control the alignment on a per item basis.
#a {
display:flex;
align-items:flex-start;
align-content:flex-start;
}
#a > div {
background-color:red;
padding:5px;
margin:2px;
}
#a > #c {
align-self:stretch;
}
<div id="a">
<div id="b">left</div>
<div id="c">middle</div>
<div>right<br>right<br>right<br>right<br>right<br></div>
</div>
css-tricks has an excellent article on the topic. I recommend reading it a couple of times.
