Adjacent sibling selector in CSS

The adjacent sibling selector + allows you to select an element by its adjacent sibling above.

Syntax

selector1 + selector2 {
	
}

Let's select all the p tags that immediately follow the h2 tags and color them red:

<h2>text</h2>
<p>
	+
</p>
<p>
	-
</p>
<p>
	-
</p>

h2 + p {
	color: red;
}

Let's select all p tags immediately after elements with the class .test and color them red:

<p class="test">
	text
</p>
<p>
	+
</p>
<p>
	-
</p>

.test + p {
	color: red;
}

Let's select all elements with the class .elem immediately after elements with the class .test and color them red:

<p class="test">
	text
</p>
<p class="elem">
	+
</p>
<p>
	-
</p>

.test + .elem {
	color: red;
}
