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 set the bottom edge position in percentage</title><!-- Sets the title of the HTML document -->
<style type="text/css"> /* Begins a CSS style block */
div.xyz1 { /* Defines a CSS rule for div elements with class "xyz1" */
position: absolute; /* Sets the position of the element to absolute */
width: 200px; /* Sets the width of the element */
height: 100px; /* Sets the height of the element */
border: 3px solid #FF0000; /* Sets the border properties of the element */
background-color: #46C3FF; /* Sets the background color of the element */
bottom: 50%; /* Sets the bottom edge of the element to be positioned 50% from the bottom of its containing block */
}
</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 a paragraph with the text "w3resource Tutorial" -->
<div class="xyz1">This division element position : percentage</div><!-- Displays a div element with class "xyz1" and the specified text -->
</body><!-- Ends the body section of the HTML document -->
</html><!-- Ends the HTML document -->

Explanation:

The position: absolute; CSS property sets the positioning method of the element to absolute, positioning it relative to its nearest positioned ancestor.
The width: 200px; CSS property sets the width of the element to 200 pixels.
The height: 100px; CSS property sets the height of the element to 100 pixels.
The border: 3px solid #FF0000; CSS property sets the border properties of the element to a 3-pixel wide solid red border.
The background-color: #46C3FF; CSS property sets the background color of the element to light blue (#46C3FF).
The bottom: 50%; CSS property sets the bottom edge of the element to be positioned 50% from the bottom of its containing block, which in this case is the viewport.
