Using HTML for code punctuation involves <code> for inline text, <pre> for preformatted blocks preserving whitespace and line breaks, and <samp> for demonstrating sample program output:

<code>// Inline 'let x = 10;' like inline skating: quick, smooth & fits right in.</code> 
<pre>// Block 'function demo() { return x; }': like LEGO blocks - they stick together.</pre> 
<samp>// Sample 'Output: 10': echoes the program's heart, beats and all.</samp>

Applying HTML tags for structured code

Proper HTML tag usage optimizes readability and codifies document structure:

<code> is used for inline code, ensuring snug fit within text that wraps to screen size.
<pre><code> is perfect for block code snippets, maintaining format and spaces, preventing word wrap.
<samp> is best for depicting results or output from code execution.

With CSS styling, create visual distinction and manage behavior of code snippets such as background colors.

Tweaking CSS for desirable code representation

Control the presentation and functionality of code blocks using CSS properties and techniques:

Apply white-space: pre-wrap; with <pre> to handle super long lines.
Leverage display: block; and white-space: pre-wrap; to make <code> suitable for code blocks rather than inline snippets.
Use background-color to keep your code snippets from playing hide and seek with the text.

Simplify HTML structure with data attributes or preserve code with <textarea readonly> for displaying HTML code without executing it.

Handling special code representation needs

Sometimes, you need more than standard tags to meet your specific needs:

Create custom tags like <codenza> for custom snippet styling. Just remember to define them in your CSS.
For better line wrapping control, use CSS properties over <br> tags.

Ensuring code maintainability and simplicity

When writing HTML for others:

Maintain a simple structure to save future you, or others, from deciphering your code hieroglyphics.
Write HTML that a non-technical person can interpret. Avoid verbose HTML.
Keep consistency in code presentation—a wanderer's map guiding future maintainers.
Keep it clean and clear. Elegance over grandeur--that's your motto.

Testing puts perfection in perspective

Always verify your code representation:

Share and demonstrate your snippets using online tools like jsfiddle.net.
A quick browser check using the data: URI protocol gives a preview of your snippet's appearance.
Regular testing ensures your snippets don't go to a masquerade ball, maintaining a consistent look across all platforms.
