Some basic documentation can be found here.

Html – Can you create css-grid-like templates with a one-row flexbox layout?

Can I make this structure with flexbox?

enter image description here

I give an example below with grid, but I want make this with flexbox.

.container {
    display: grid;
    grid-template-columns: auto auto auto;
    gap: 10px;
}
.grid-item {
    background-color: aquamarine;
}
.small {
    height: 200px;
}
.big {
    grid-row: span 10;
}
<div class="container">
    <div class="grid-item small">Cell 1</div>
    <div class="grid-item small">Cell 2</div>
    <div class="grid-item big">Cell 3</div>
    <div class="grid-item small">Cell 4</div>
    <div class="grid-item small">Cell 5</div>
    <div class="grid-item small">Cell 6</div>
    <div class="grid-item small">Cell 7</div>
    <div class="grid-item small">Cell 8</div>
    <div class="grid-item small">Cell 9</div>
    <div class="grid-item small">Cell 10</div>
    <div class="grid-item small">Cell 11</div>
    <div class="grid-item small">Cell 12</div>
</div>

What I want to achieve with flexbox:

width: 100%;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: flex-start;

and

<div class="item">1</div>
<div class="item">2</div>
<div class="item big">3</div>
<div class="item">4</div>
<div class="item">5</div>
<div class="item">6</div>
<div class="item">7</div>

This is challenging because

  1. is with display flex
  2. in one row

    So far I know, this is the only way to do it using Flexbox as it is one-dimensional.

    *{
    margin: 0;
    padding: 0;
}

.flex-container{
  display: flex;
  flex-wrap: wrap;
  gap: 10px;
}

.flex-inner-container {
  display: flex;
  flex-wrap: wrap;
  gap: 10px;
  flex: 1 0 calc(50% - 10px);
}   

.flex-inner-container .item {
  background-color: aquamarine;
  flex: 1 0 calc(50% - 10px);
  height: 200px;
}

.big {
    flex: 1 0 calc(50% - 10px);
    background-color: aquamarine;
}
    <div class="flex-container">
    <div class="flex-inner-container">
        <div class="item">1</div>
        <div class="item">2</div>        
        <div class="item">4</div>
        <div class="item">5</div>
        <div class="item">6</div>
        <div class="item">7</div>
    </div>

    <div class="item big">3</div>
</div>
