Why Are There Gaps Between My Inline-Block Elements?

Inline-Block Elements Spacing Issue

Inline-block elements, as their name suggests, are displayed as inline elements but can also have a fixed width and height, making them behave like block elements. However, in some cases, these elements may exhibit unexpected spacing between them.

This spacing arises because inline-block elements are whitespace-dependent, meaning they inherit whitespace from their containing element. In the example provided:

li {
  border: 1px solid black;
  display: inline-block;
  height: 25px;
  list-style-type: none;
  text-align: center;
  width: 50px;
}

The font used for the text within the list items has a default whitespace setting, typically a 4px space. This spacing is inherited by the inline-block elements, resulting in unnecessary spaces between them.

To address this issue, several approaches can be taken:

• Combine list items: Remove the line breaks between list items and inline them in a single line.
• Block list tags: Move the start and end tags of the list items to the same line, removing the whitespace between them.
• Reset font-size: Add font-size: 0; to the parent element of the list items. This resets the inherited whitespace setting. Then, set the font size for the content within the list items to the desired value.

The preferred method is the last approach, as it maintains the readability of the HTML while resetting the whitespace setting. By setting font-size: 0; on the parent element, the whitespace is effectively eliminated, and the true width of the inline-block elements is displayed accurately.
