How Can I Achieve Equal Spacing Between Flexbox Items, Including the First and Last?

Ensuring Equal Spacing in Flexbox Items

When utilizing flexbox to align elements, it's common to encounter situations where you desire equal spacing between all items, including the first and last.

The "Space-Around" Issue

The CSS property justify-content: space-around appears to distribute items evenly with equal space around them. However, as stated in an article, the first item has one unit of space against the container edge, resulting in unequal spacing between items.

Solving the Problem with Pseudo-Elements

One approach to achieving equal spacing involves utilizing pseudo-elements. By adding ::before and ::after pseudo-elements to the flex container, we can insert zero-width markers that count as flex items.

By applying justify-content: space-between and specifying zero width for the pseudo-elements, the visible flex items will appear evenly spaced.

flex-container {
  display: flex;
  justify-content: space-between;
}

flex-container::before {
  content: "";
  width: 0;
}

flex-container::after {
  content: "";
  width: 0;
}
