Make a div span two rows in a grid

Question

I have a page full of blocks which pile up with display: inline-block. I want to make some four or two times bigger, so I used float: left or right to put other blocks around.

My problem is if I have a five-element row, how could I put a bigger element in the middle of it? (as float put it naturally on the side).

Here's an example snippet:

#wrapper{
  width: 516px;
}
.block{
  display: inline-block;
  width: 90px;
  height: 50px;
  margin: 5px;
  background-color: red;
}
.bigger{
  height: 110px;
}

<div id="wrapper">
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block bigger"></div>
  <div class="block"></div>
  <div class="block"></div>
</div>

Here's what I would like to have from the snippet above

Flexbox Solution

You have fixed heights on your child elements (.block). Based on that information, we can extrapolate the height of the container (#wrapper).

By knowing the height of the container, your layout can be achieved using CSS Flexbox with flex-direction: column and flex-wrap: wrap.

A fixed height on the container serves as a breakpoint, telling flex items where to wrap.

#wrapper {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  height: 120px;
  width: 516px;
}
.block {
  width: 90px;
  flex: 0 0 50px;
  margin: 5px;
  background-color: red;
}
.bigger {
  flex-basis: 110px;
}

<div id="wrapper">
  <div class="block"></div>
  <div class="block"></div>
  <div class="block bigger"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
  <div class="block"></div>
</div>

Here's an explanation why flex items can't wrap unless there's a fixed height/width on the container: https://stackoverflow.com/a/43897663/3597276
