<title>How to set the tab-size of a paragraph element</title><!-- Sets the title of the document -->
<style type="text/css"> /* Starts CSS styling */
p#tab { /* Styles paragraphs with the id "tab" */

</p><!-- Ends the "tab" paragraph -->
<p id="tab1"><!-- Displays a paragraph with the id "tab1" -->

</p><!-- Ends the "tab1" paragraph -->
</body><!-- Ends the body section -->

Explanation:

This HTML document demonstrates how to set the tab size of paragraph elements using CSS.
CSS comments are added to explain each section of the code.
Two CSS selectors are defined:

p#tab styles paragraphs with the id "tab".
p#tab1 styles paragraphs with the id "tab1".

The tab-size property is used to specify the width of tab characters in the paragraphs.
Vendor-specific prefixes (-moz- and -o-) are included to ensure compatibility with older versions of Firefox and Opera browsers.
The white-space: pre-wrap; property ensures that white-space is preserved in the paragraphs and line breaks are honored.
