Creating a Flexbox Layout Using CSS

The flexbox is another layout model in CSS that provides a more flexible approach when designing and structuring complex layouts. It is particularly suited for creating one-dimensional layouts, as we will see later.

Just like a grid layout, a flexbox layout consists of a flex container and several flex items. The container should have its display property set to flex, and all of its direct children automatically become flex items.

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

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

Flex direction

With a flex layout, instead of rows and columns, you must define a flex-direction and a flex-wrap. The flex-direction specifies in which direction the container should stack its flex items.

The accepted values are:

• column

.container {
  flex-direction: column;
}

• column-reverse

.container {
  flex-direction: column-reverse;
}

• row

.container {
  flex-direction: row;
}

• row-reverse

.container {
  flex-direction: row-reverse;
}

Flex wrap

The flex-wrap property determines whether the flex items should wrap (automatically change to the next line when there is insufficient space).

• wrap

.container {
  flex-wrap: wrap;
}

• nowrap

.container {
  flex-wrap: nowrap;
}

• wrap-reverse

.container {
  flex-wrap: wrap-reverse;
}

The flex-flow is a shorthand for both flex-direction and flex-wrap properties.

.container {
  flex-flow: column wrap;
}
