Better way to set distance between flexbox items
CSS gap
property:
There is a new gap
CSS property for multi-column, flexbox, and grid layouts that works in newer browsers now! (See Can I use link 1; link 2). It is shorthand for row-gap
and column-gap
.
#box {
display: flex;
gap: 10px;
}
CSS row-gap
property:
The row-gap
CSS property for both flexbox and grid layouts allows you to create a gap between rows.
#box {
display: flex;
row-gap: 10px;
}
CSS column-gap
property:
The column-gap
CSS property for multi-column, flexbox and grid layouts allows you to create a gap between columns.
#box {
display: flex;
column-gap: 10px;
}
Example:
#box {
display: flex;
flex-wrap: wrap;
width: 200px;
background-color: red;
gap: 10px;
}
.item {
background: gray;
width: 50px;
height: 50px;
border: 1px black solid;
}
<div id='box'>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
</div>
- Flexbox doesn't have collapsing margins.
- Flexbox doesn't have anything akin to
border-spacing
for tables (edit: CSS propertygap
fulfills this role in newer browsers, Can I use)
Therefore achieving what you are asking for is a bit more difficult.
In my experience, the "cleanest" way that doesn't use :first-child
/:last-child
and works without any modification on flex-wrap:wrap
is to set padding:5px
on the container and margin:5px
on the children. That will produce a 10px
gap between each child and between each child and their parent.
Demo
.upper {
margin: 30px;
display: flex;
flex-direction: row;
width: 300px;
height: 80px;
border: 1px red solid;
padding: 5px; /* this */
}
.upper > div {
flex: 1 1 auto;
border: 1px red solid;
text-align: center;
margin: 5px; /* and that, will result in a 10px gap */
}
.upper.mc /* multicol test */ {
flex-direction: column;
flex-wrap: wrap;
width: 200px;
height: 200px;
}
<div class="upper">
<div>aaa<br/>aaa</div>
<div>aaa</div>
<div>aaa<br/>aaa</div>
<div>aaa<br/>aaa<br/>aaa</div>
<div>aaa</div>
<div>aaa</div>
</div>
<div class="upper mc">
<div>aaa<br/>aaa</div>
<div>aaa</div>
<div>aaa<br/>aaa</div>
<div>aaa<br/>aaa<br/>aaa</div>
<div>aaa</div>
<div>aaa</div>
</div>
