Flexbox 3 Divs, Two Columns, One With Two Rows

I am trying to take

Three sequential divs and turn it into below. Where red is div 1, green is div 2, blue

Solution 1:

The Legit Method: *Recommended

.flex-row {
    flex-direction: row;
    display: flex;
}

.flex-column {
    flex-direction: column;
    display: flex;
}

.flex-body {
    display: flex;
}

.flex-bodydiv:not([class*="flex"]) {
    border: 1px solid white;
    flex: 11200px;
    width: 300px;
}

<divclass="flex-body"><divclass="flex-row"><divstyle="background: #0980cc;"></div></div><divclass="flex-column"><divstyle="background: #09cc69;"></div><divstyle="background: #cc092f;"></div></div></div>

The Hackish Method: *Not Recommended (I'm sure you'll notice why)

.flex-body {
    display: flex;
    flex-direction: row-reverse;
    flex-wrap: wrap;
    justify-content: flex-end;
    align-content: stretch;
    align-items: stretch;
    transform: rotate(90deg);
    max-width: 500px;
    margin: auto;
}

.flex-bodydiv {
    border: 1px solid white;
    height: 300px;
    flex: 11200px;
}

.flex-bodydiv:last-of-type {
    flex: 11300px;
    height: 300px;
}

<divclass="flex-body"><divstyle="background: #0980cc;"></div><divstyle="background: #09cc69;"></div><divstyle="background: #cc092f;"></div></div>

Solution 2:

After thinking about this a little more, it is possible with flexbox. The container just has to have a defined height (%, px or vh) will work.

body {
  display: flex;
  flex-wrap: wrap;
  flex-direction: column;
  height: 100vh;
}

.a {
  flex: 00100%;
  background: red;
}

.b, .c {
  flex: 0050%;
  background: green;
}

.c {
  background: blue;
}

Solution 3:

Using flexbox is very simple, you just need a container for these three div elements.

Let's define a div with a .box class and add the div elements. Also let's add three classes for the colors: .red, .green and .blue and two classes to handle the columns left and right.

<divclass="box"><divclass="left red"></div><divclass="right green"></div><divclass="right blue"></div></div>

Now we define the box class as a flexbox:

.box {
    display: flex;
    ...
}

Then we define the direction as column (vertical) and if it can be flowed wrap:

.box {
    ...
    flex-flow: column wrap;
    ...
}

Also, we can define the dimensions of the div elements. left will be 45% of the parent width and 100% of the parent height.

.left {
    width: 45%;
    height: 100%;
}

While right will be 55% of the parent width and 50% (half) of the parent height.

.right {
    width: 55%;
    height: 50%;
}

Full example:

.box {
  display: flex;
  flex-flow: column wrap;
  width: 400px;
  height: 100px;
}

.red {
  background: #cc092f;
}

.green {
  background: #09cc69;
}

.blue {
  background: #0980cc;
}

.left {
  width: 45%;
  height: 100%;
}

.right {
  width: 55%;
  height: 50%;
}

<divclass="box"><divclass="left red"></div><divclass="right green"></div><divclass="right blue"></div></div>
