CSS: Comments

Comments in CSS are non-executable lines of text that are used to add notes, explanations, or reminders within the CSS code. They are ignored by the browser and do not affect how the styles are applied to the web page. Comments are purely for the benefit of developers and designers to document their code and make it more understandable for themselves or others who may work on the project.

There are two types of comments in CSS:

• Single-line Comments: Single-line comments start with // and continue until the end of the line. They are useful for adding brief comments or explanations on a single line.

/* This is a multi-line comment */
/* This is another multi-line comment */
p {
   color: blue; /* This is a single-line comment */
   font-size: 16px;
}

• Multi-line Comments: Multi-line comments start with /* and end with */. They can span multiple lines and are typically used for longer comments or explanations that extend over several lines.

/* This is a multi-line comment
  that spans multiple lines
  and provides detailed explanations */
/* You can also use multi-line comments
  to temporarily disable or "comment out"
  blocks of CSS code */
/* 
body {
   background-color: lightgray;
}
*/

Comments are helpful for:

• Documenting code: Adding comments to explain the purpose of specific styles or sections of code.
• Providing reminders: Writing notes to remind yourself or others about future changes or improvements.
• Disabling code temporarily: Commenting out code allows you to disable styles temporarily without deleting them, which can be useful for testing or troubleshooting.

Including comments in your CSS code can improve code readability, collaboration, and maintenance, making it easier to understand and work with stylesheets in complex projects.
