justify-content in CSS Flexbox – How to Layout Flex Children

justify-content specifies how browsers should position a flexible container's items along the flexbox's main axis.

The justify-content property accepts the following values:

• flex-start
• center
• flex-end
• space-between
• space-around
• space-evenly

Let's discuss the six values.

What Is justify-content: flex-start in CSS Flexbox?

flex-start is justify-content's default value. It aligns a flexible container's items with the main-start edge of the flexbox's main axis.

Here's an example:

CSS

section {
  display: flex;
  justify-content: flex-start;
  background-color: orange;
  margin: 10px;
}

div {
  border: 1px solid black;
  background-color: purple;
  color: white;
  padding: 10px;
  border-radius: 5px;
}

What Is justify-content: space-between in CSS Flexbox?

space-between does the following:

• It aligns a flexible container's first item with the main-start edge of the flexbox's main axis.
• It aligns the container's last item with the main-end edge of the flexbox's main axis.
• It creates even spacing between each pair of items between the first and last item.

Here's an example:

CSS

section {
  display: flex;
  justify-content: space-between;
  background-color: orange;
  margin: 10px;
}

div {
  border: 1px solid black;
  background-color: purple;

What Is justify-content: space-around in CSS Flexbox?

space-around assigns equal spacing to each side of a flexible container's items.

Therefore, the space before the first item and after the last element is half the width of the space between each pair of elements.

justify-content's space-around value assigns equal spacing to each side of the flexbox's items

Here's an example:

CSS

section {
  display: flex;
  justify-content: space-around;
  background-color: orange;
  margin: 10px;
}

div {
  border: 1px solid black;
  background-color: purple;
  color: white;
  padding: 10px;
  border-radius: 5px;
}
