Flexbox - two small items next to one large - css

Question

I need to have a layout that looks like this on mobile
-----
| 1 |
-----
| 2 |
-----
| 3 |
-----
And like this on desktop:
---------
| | 1 |
| 2 |---|
| | 3 |
| |----
| |
-----
I decided to use flexbox, my code so far:
<div class="row">
<div class="col-xl secound">2</div>
<div class="col-sm first">1<br>2<br>3<br>4</div>
<div class="col-xl third">3</div>
</div>
.row {
display: flex;
flex-flow: row wrap;
}
.col-sm,
.col-xl {
width: 100%;
}
.col-sm {
background: yellow;
}
.col-xl {
&.secound {
background: #ccc;
}
&.third {
background: #aaa;
}
}
#media (min-width: 700px) {
.col-sm {
width: 25%;
background: yellow;
order: 1;
}
.col-xl {
width: 75%;
&.secound {
background: #ccc;
order: 2;
}
&.third {
background: #aaa;
order: 3;
}
}
}
Unfortunately, I can't slide column "3" under "1". What should I do?

Answer 1

You can try using float for desktop, and using flexbox with order set for mobile.
jsFiddle
.item-1 {background:aqua;}
.item-2 {background:gold;}
.item-3 {background:pink;}
.row {
overflow: hidden;
}
.item {
width: 50%;
}
.item-2 {
float: left;
}
.item-1,
.item-3 {
overflow: hidden;
}
#media (max-width: 768px) {
.row {
display: flex;
flex-direction: column;
}
.item {
width: auto;
float: none;
}
.item-1 {
order: -1;
}
}
<div class="row">
<div class="item item-2">2<br><br><br></div>
<div class="item item-1">1</div>
<div class="item item-3">3</div>
</div>

Answer 2

You could align .third on the right by using flex property justify-content.
You're CSS would look something like this:
.row{
display: flex;
flex-flow: row wrap;
justify-content: flex-end;
}
.row > div{
flex: 0 0 50%;
}
For changing order you can use the order property:
.first{ order: 1; }
.second{ order: 2; }
.third{ order: 3; }
#media (min-width: 700px){
.first{ order: 2; }
.second{ order: 1; }
.third{ order: 3; }
}
Check the fiddle
On CSS-tricks you can find a great guide for using Flex properties.

Answer 3

There are few things I've given sizes too just for the sake of the demo but it will still work without the sizes.
You will need to give your container a size but that can be 100vh/100vw or even percentage rather than actual pixels.
body {
margin: 0;
}
.container {
display: flex;
flex-wrap: wrap;
flex-direction: column;
height: 600px;
width: 100%;
}
.item-1,
.item-2,
.item-3 {
width: 100%;
font-size: 80px;
color: #fff;
text-align: center;
}
.item-1 {
line-height: 100px;
height: 100px;
background: #00bcd5;
}
.item-2 {
line-height: 200px;
height: 200px;
background: #8bc24a;
}
.item-3 {
line-height: 300px;
height: 300px;
background: #fec107;
}
#media (min-width: 700px) {
.item-1,
.item-2,
.item-3 {
width: 50%;
}
.item-1,
.item-3 {
order: 1;
}
.item-2 {
height: 100%;
line-height: 1em;
}
}
<div class="container">
<div class="item-1">1</div>
<div class="item-2">2</div>
<div class="item-3">3</div>
</div>
Hope this is what you're looking for.

Answer 4

You could use float: right for all three elements instead. Together with the appropriate width definitions in media queries, this should work.

Grid:
/* Column */
.item {
width: 100%;
}
/* Wrap */
.row {
display: flex;
flex-flow: column wrap;
}
/* Responsive */
#media screen and (min-width: 700px){
.row {
flex-flow: row wrap;
justify-content: flex-end;
}
.item { width: 50%;}
.item-1 { order: 2; }
.item-2 { order: 1; }
.item-3 { order: 3; }
}
/* Custom style */
.item {

</div>
<div class="item hidden item-1">1</div>

</div>

Answer 6

How about using absolute position?
In your media query change the .row class to this:
.row {
position: relative;
align-items: flex-end;
}
And your .item-2 to:
.item-2 { order: 1; position: absolute; top: 0; left: 0; }
/* Column */
.item {
width: 100%;
}
/* Wrap */
.row {
display: flex;
flex-flow: column wrap;
}
/* Responsive */
#media screen and (min-width: 700px){
.row {
position: relative;
align-items: flex-end;
}
.item { width: 50%;}
.item-1 { order: 2; }
.item-2 { order: 1; position: absolute; top: 0; left: 0; }
.item-3 { order: 3; }
}
/* Custom style */
.item {
color: #fff;
display: block;
text-align: center;
line-height: 200px;
font-size: 3rem;
}
.item-1 {
background: #00bcd5;
}
.item-2 {
background:#8bc24a;
}
.item-3 {
background:#fec107;
}
<div class="row">
<div class="item item-1">1</div>
<div class="item item-2">2
<br>2</div>
<div class="item item-3">3</div>
</div>
