To set the minimal distance between flexbox items I'm using margin: 0 5px
on .item
and margin: 0 -5px
on container. For me it seems like a hack, but I can't find any better way to do this.
border-spacing
for tables (except for CSS property gap
which isn't supported in Safari, caniuse)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.
.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>
