- Avoid Redundancy: Don’t comment on every line of code if it’s self-explanatory. Focus on explaining complex or non-obvious parts.
- Maintain Consistency: Use a consistent style of commenting throughout your codebase in order to improve the readability and maintenance.
- Consider Accessibility: Remember that comments are part of the HTML document and may be accessible to users with assistive technologies. Avoid including sensitive or irrelevant information.

<section class=”main-content”>
<h2>About Us</h2>
