Comments in CSS are non-executable lines of text that are ignored by the browser. They serve the sole purpose of providing information and context to developers, making it easier to understand and maintain the code. CSS comments are not rendered on the webpage, ensuring that they do not affect the visual presentation or performance of the site.
In the below PDF we discuss about CSS Comments in detail in simple language, Hope this will help in better understanding.
Types of CSS Comments:
CSS comments can be written in two ways:
1. Single-line comments: Use /*….. */ to enclose a single-line comment.
/* This is a single-line comment */
2. Multi-line comments: Use /* to start the comment and */ to end it for multi-line comments.
This is a multi-line comment
spanning multiple lines for better readability.
Advantage of CSS Comments:
- Code Documentation:
CSS comments act as a form of documentation, providing insights into the purpose and functionality of different sections of your stylesheet. This is particularly useful for teams working on collaborative projects or when revisiting code after a significant period.
- Troubleshooting and Debugging:
Comments can help isolate and identify specific sections of code during troubleshooting or debugging. By commenting out or adding comments to different parts of the stylesheet, developers can pinpoint issues more efficiently.
- Future Reference:
When working on long-term projects or coming back to your code after a hiatus, comments become a valuable resource. They serve as a roadmap, guiding you through the logic and decisions made during the development process.
- Collaboration and Communication:
CSS comments facilitate effective communication among team members. Developers can use comments to explain their thought process, flag potential issues, or suggest improvements. This collaborative aspect is essential for maintaining a cohesive and productive development environment.
- Version Control:
Comments also play a role in version control systems. When committing changes, descriptive comments can help team members understand the purpose and impact of specific modifications, streamlining the collaborative development process.
A CSS comment is a way to include explanatory or descriptive text within the style sheet’s code. Comments are not rendered on the webpage and are solely for the benefit of developers.
CSS comments are useful for adding notes, explanations, or reminders within the code. They help make the code more readable, understandable, and maintainable, especially when working in a team or revisiting the code after some time.
