How to Make All Elements the Same Width as the Widest in CSS Without JavaScript?

How to Make Every Element the Same Width as the Widest Element Using CSS

In certain scenarios, it becomes necessary to ensure that all elements in a layout have the same width as the widest element. This can be achieved in CSS without resorting to JavaScript, unlike the popular example that utilizes JavaScript to achieve this effect.

The essence of this approach lies in understanding how flexbox works. By implementing the following CSS rules, we can create the desired behavior:

.list-container {
  display: inline-flex;
  flex-direction: row;
  justify-content: center;
}

.list {
  display: flex;
  flex-direction: column;
}

.list-item {
  text-transform: capitalize;
  background-color: rgb(200, 30, 40);
  font-size: 1.3em;
  text-align: left;
  padding: 10px;
  margin: 1px;
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: flex-start;
}

By utilizing these CSS rules, we can achieve the following results:

1. Flexbox container (.list-container): The parent container utilizes inline-flex to align child elements (.list) horizontally on the same line.
2. List container (.list): This container uses flex-direction: column to align list items (.list-item) vertically in a column.
3. List items (.list-item): These elements have several styling properties, including a fixed width that allows all items to appear equal in size. Additionally, flex-wrap: wrap ensures that the items flow onto multiple lines if necessary, mimicking the behavior of the JavaScript-based example.

Here is an example HTML structure that demonstrates the application of this method:

<div class="list-container">
  <div class="list">
    <div class="list-item">fresh figs</div>
    <div class="list-item">pine nuts</div>
    <div class="list-item">honey</div>
    <div class="list-item">balsamic vinegar</div>
  </div>
</div>

<div class="list-container">
  <div class="list">
    <div class="list-item">fresh figs</div>
    <div class="list-item">pine nuts</div>
    <div class="list-item">honey</div>
    <div class="list-item">balsamic vinegar</div>
  </div>
</div>

In conclusion, it is possible to replicate the functionality of the JavaScript-based example solely using CSS. By employing the principles of flexbox, we can ensure that all elements within a given layout have the same width as the widest element, creating a visually consistent and organized appearance.
