Solution:

HTML Code:

<!DOCTYPE html><!-- Declares the document type as HTML -->
<html><!-- Root element of the HTML document -->
<head><!-- Contains metadata about the HTML document -->
<title>How to specify a right double border</title><!-- Sets the title of the HTML document -->
<style type="text/css"> /* Begins a CSS style block */
h1  {border-style: solid; /* Defines a CSS rule for all h1 elements, setting their border style to solid */
border-width: 5px; /* Sets the width of the border of h1 elements to 5 pixels */
}
h1.double {border-right-style:double;} /* Defines a CSS rule for h1 elements with the class 'double', setting their right border style to double */
</style><!-- Ends the CSS style block -->
</head><!-- Ends the head section of the HTML document -->
<body><!-- Contains the content of the HTML document -->
<p>w3resource Tutorial</p><!-- Displays the text 'w3resource Tutorial' within a paragraph element -->
<h1 class="double">Double right border</h1><!-- Displays the text 'Double right border' within an h1 element with the class 'double' -->
</body><!-- Ends the body section of the HTML document -->
</html><!-- Ends the HTML document -->

Explanation:

The HTML document is structured with essential elements such as html, head, title, style, and body.
CSS is used to style all h1 elements, setting their border style to solid and their border width to 5 pixels.
A specific CSS rule is defined for h1 elements with the class double, setting their right border style to double.
The text "w3resource Tutorial" is displayed within a paragraph element, and "Double right border" is displayed within an h1 element with the class double.
