How to Force Line Breaks in Inline Element Lists After Specific Items?

Line Breaking in Inline-Block Content

Consider a situation where HTML content contains a list of items represented using inline-block li elements. The goal is to inject a line break after the third li item to create a three-column effect.

Limitations of CSS

The premise is that adding a line break between specific inline-block elements directly using CSS is not feasible. Methods like inserting an :after pseudo-element with content: "xxx" and display: block or selecting the third li with :nth-child will not suffice.

Workaround for Inline Elements

However, there is a workaround if the li elements are changed from display: inline-block to display: inline. By adding CSS as follows, a line break can be injected after the third li element:

<code class="CSS">li { 
    display: inline; 
}
li:nth-child(3):after { 
    content: "\A";
    white-space: pre; 
}</code>

In this example, "A" inserts a line break, and white-space: pre preserves it within the inline context.

Conclusion

While it is not possible to directly inject line breaks between inline-block elements using CSS, this workaround demonstrates that it is feasible with inline elements, providing a potential solution for the need to break content into columns or alter the flow within inline content.
