Use the CSS :nth-last-of-type(n) selector to select every <p> element that is the second <p> element of its parent, counting from the last child.
Example
You can try to run the following code to implement the :nth-last-of-type(n) selector:
<!DOCTYPE html>
<html>
<head>
<style>
p:nth-last-of-type(2) {
background: blue;
color: white;
}
</style>
</head>
<body>
<p>This is demo text 1.</p>
<p>This is demo text 2.</p>
<p>This is demo text 3.</p>
<p>This is demo text 4.</p>
<p>This is demo text 5.</p>
</body>
</html>
