How Can I Make Flexbox Items Occupy Equal Widths?

Distributing Flexbox Items Uniformly

Flexbox has gained popularity as a versatile layout method, yet it tends to distribute space around items evenly rather than the items themselves. To address this challenge, let's explore a solution to ensure all flexbox items occupy the same width.

Flexbox operates on the principle of growing and shrinking items based on their flex-grow property. By default, flex-grow is set to 0, causing items to be rendered with their natural widths. However, we can modify this property to achieve our desired outcome.

To create items with equal widths, set their flex-basis to 0. This establishes a common starting point for all elements. Additionally, allow the items to grow by setting flex-grow to 1. This will ensure that they expand equally to fill the available space.

The following CSS code demonstrates this approach:

.header {
  display: flex;
}

.item {
  flex: 1 1 0px;
  text-align: center;
  border: 1px solid black;
}

By setting flex-basis to 0 and flex-grow to 1, all items within the .item class will have an equal amount of space, regardless of their content. This eliminates the uneven distribution observed in the original example.

Note: Some IDEs and linters may suggest omitting the 'px' unit from flex. However, retaining it ensures correct rendering in Internet Explorer.
