Key Points About HTML Comments

• Comments are ignored by web browsers.
• They aid in code readability and documentation.
• HTML comments are denoted by <!-- content -->.
• The shortcut key for commenting out code is Ctrl + /.
• HTML supports both single-line and multi-line comments.

Types of Comments in HTML

HTML primarily supports two types of comments:

Single-line Comments

Single-line comments are used to add comments on a single line. They start with <!-- and end with -->. Single-line comments are ideal for short notes or annotations.
Example:

<!-- This is a single-line comment -->

Multi-line Comments

Multi-line comments span across multiple lines, making them ideal for detailed explanations or temporarily disabling blocks of code.
Example:

<!-- 
  This is a multi-line comment.
  It spans multiple lines.
-->

Best Practices for Using Comments

• Use comments to explain complex code or provide context.
• Avoid excessive comments that state the obvious.
• Update comments when modifying code to maintain accuracy.
• Use comments to disable code temporarily during testing or debugging.
