Writing CSS is not only about making styles work.
It is also about making your code easy to read and understand.
Why Clean CSS Matters
Clean CSS helps:
- You understand your own code later
- Other developers work with you
- Reduce mistakes and confusion
What Are CSS Comments
Comments are notes written inside CSS.
They are ignored by the browser and only for humans to read.
You can write comments to explain what your styles do.
Where to Use Comments
Use comments to:
- Describe sections of your stylesheet
- Explain complex styles
- Leave notes for teammates
This makes your CSS easier to navigate.
Why Formatting Matters
Formatting means how your code is spaced and aligned.
Good formatting makes CSS readable at a glance.
Bad Formatting Example
Hard-to-read CSS causes mistakes.
This code works, but it is hard to read.
This version is clean and professional.
Best Practices for Formatting
- Use one rule per line
- Indent properties properly
- Leave space between sections
Why This Matters for Jobs
Companies expect developers to write clean code.
Readable CSS shows professionalism and experience.
Practice Task
Take a small CSS file and:
- Add comments for each section
- Format it to be clean and readable
