To style, more than one element, use a comma. Separate each element with the comma to achieve this. You can try to run the following code to select <div> and <p> elements,
Example
<!DOCTYPE html>
<html>
<head>
<style>
div, p {
color: blue;
background-color: orange;
}
</style>
</head>
<body>
<h1>Demo Website</h1>
<h2>Fruits</h2>
<p>Fruits are good for health.</p>
<div>
<p>This is demo text.</p>
</div>
</body>
</html>
