Can CSS Force Line Breaks within Inline-Block Elements?

CSS Line Break Insertion within Inline-block Elements

In this case, you want to force a line break after a specific inline-block element without resorting to float, fixed-width blocks, or display:table-cell. This question delves into the theoretical possibility of injecting a line break inside inline content using CSS.

The Problem

Given the provided HTML and CSS, the challenge is to create three columns of list items without using invalid syntax or specific layout techniques.

Potential Solution

An approach was attempted using CSS after pseudo-element:

li:nth-child(4):after { content:"xxx"; display:block }

However, this did not produce the desired result.

The Answer

Based on the provided information, it is not possible to force a line break after a specific inline-block element using pure CSS. This is because inline-block elements are inherently laid out side-by-side. To achieve the desired layout, alternative methods such as float or display:table-cell must be used.
