General sibling selector in CSS

The general sibling selector ~ selects all elements that come after a given element within the same parent.

Syntax

selector1 ~ selector2 {
	
}

Let's select all the p tags that come after the h2 tags and color them red:

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

h2 ~ p {
	color: red;
}

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

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

.test ~ p {
	color: red;
}

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

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

.test ~ .elem {
	color: red;
}
