In CSS, comments are created using the syntax /* comment here */. This particular format enables developers to include remarks or explanations within the CSS code that will not be processed by the browser. This is useful for documenting the purpose of specific styles, providing context for future reference, or temporarily disabling certain styles during development without deleting them.

The opening /* indicates the start of the comment, and the closing */ signifies the end. Everything in between these two markers is ignored by the CSS interpreter, thus it does not affect the style of the HTML document.

Other methods shown in the choices are not valid for CSS commenting. Option A uses //, which is a style commonly used in languages like JavaScript for single-line comments but is not applicable in CSS. Option C, using <!-- comment here -->, is specific to HTML and is not suitable for CSS. Finally, option D, which uses #, is used for comments in some scripting languages like Python, but it does not apply to CSS syntax either.
