Adjacent selector in CSS

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

Example

Let's look at all the p tags immediately after the h2 tags and color them red:

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

h2 + p {
	color: red;
}

Example

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

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

.test + p {
	color: red;
}

Example

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

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

.test + .elem {
	color: red;
}

Practical tasks

Given code:

<ul>
	<li>1</li>
	<li>2</li>
	<li>3</li>
	<li>4</li>
	<li id="elem">5</li>
	<li>6</li>
	<li>7</li>
	<li>8</li>
	<li>9</li>
</ul>

Write a selector that will select the element immediately after the element #elem.

Given code:

<ul>
	<li>1</li>
	<li class="elem">2</li>
	<li>3</li>
	<li>4</li>
	<li class="elem">5</li>
	<li>6</li>
	<li>7</li>
	<li class="elem">8</li>
	<li>9</li>
</ul>

Write a selector that selects elements immediately after .elem elements.
