Why Do My 50% Width Inline-Block Elements Wrap to the Next Line?

Inline-Block Elements Break to Second Line: Understanding Width and White-Space

When attempting to create two inline-block elements with a width of 50%, it can be frustrating to encounter an issue where the second element wraps to the next line. This behavior, however, is not a result of the inline-block property but rather a consequence of white-space management.

The display:inline-block property allows elements to behave like inline elements (displayed on the same line), while also having a defined width and height. However, unlike inline elements, inline-block elements consider white-space characters in their width calculation.

In the case of two inline-block elements with a total width of 99%, such as 50% and 49%, the width measurement includes the white-space between them. As a result, the elements fit within the specified width and appear side-by-side.

On the other hand, when the total width of the elements is 100%, the white-space is also included in the calculation. Since there is no remaining space to accommodate the second element, it is forced to wrap to the next line.

To resolve this issue and prevent the second element from breaking, the white-space between the inline-block elements can be removed. By eliminating the white-space, the width calculation is adjusted accordingly, and both elements can fit comfortably on the same line.

This adjustment can be made using CSS by setting the white-space property of the parent element to nowrap or none, as seen in the example below:

#parent-container {
  white-space: nowrap;
}
