The adjacent sibling combinator (+) separates two selectors and matches the second element only if it immediately follows the first element, and both are children of the same parent element.
/* Paragraphs that come immediately after any image */
img + p {
font-style: bold;
} former_element + target_element { style properties }
li:first-of-type + li {
color: red;
}
<ul> <li>One</li> <li>Two!</li> <li>Three</li> </ul>
