How Does the \' \' Combinator in CSS Target Elements Immediately Following Siblings?

Understanding the " " Combinator in CSS

CSS employs the " " combinator to target elements that immediately follow specific siblings. For instance, in the rule "h2 p", only the p element immediately after an h2 element will be affected by the specified styles.

Visualizing the Concept

Consider the following HTML code:

<code class="html"><h2>Headline!</h2>
<p>The first paragraph.</p> <!-- Selected [1] -->
<p>The second paragraph.</p> <!-- Not selected [2] -->

<h2>Another headline!</h2>
<blockquote class="quote">
    <p>A quotation.</p> <!-- Not selected [3] -->
</blockquote></code>

When applying the "h2 p" selector:

• [1] The first paragraph (

  ) is selected because it directly follows an h2 (

  ) element.

• [2] The second paragraph (

  ) is not selected because it follows the first paragraph, not the h2 element.

• [3] The paragraph within the blockquote (

  ) is not selected as there is no h2 preceding it in the blockquote.

Comparison with "~" Combinator

The " " combinator specifically selects only elements that are immediate siblings, unlike the "~" combinator which selects all sibling elements, regardless of their position. For example, "h2 ~ p" would select both paragraphs in the above HTML, while "h2 p" would select only the first paragraph.
