CSS Tutorial - Comments

Comments are lines of code that are ignored by the compiler or interpreter and are used to describe the purpose or functionality of the code. Comments are an important aspect of programming as they help developers understand their own code and make it easier for other developers to read and modify the code.

In CSS, comments can be added using the following syntax:

/* This is a comment in CSS */

Anything written between the /* and */ symbols will be ignored by the browser and will not affect the styling of the page. Developers can use comments in CSS to explain why certain styles were applied or to make notes about future changes that need to be made.

Comments can also be used to temporarily disable or test styles without having to delete or modify the code. 

/* Explanations for First Group*/ 

.first_group {
	background: red;
	color: white;
	height: 20px;
}

/* Explanations for Second Group*/
 
.second_group {
	/* Comment */
	background: yellow; 
	color: blue; /* Comment */
	height: 30px;
}

/* Comment */

The comment "Explanations for First Group" is used to explain that the following CSS rules apply to the first group of paragraphs. Similarly, the comment "Explanations for Second Group" is used to explain that the following CSS rules apply to the second group of paragraphs.

In the second group, there are additional comments after each property. These comments provide additional information about each property. For example, the comment "Comment" is used to explain that the background property is being set to yellow.

There is a comment at the end of the code, which is simply a comment and does not provide any additional information.
