Frequently Asked Questions

What's the difference between tabs and spaces?

Tabs and spaces are both used for indentation. Tabs are single characters that can be displayed as different widths, while spaces provide consistent but larger file sizes.

Why sort properties?

Sorting properties alphabetically makes CSS more maintainable and easier to scan. It helps prevent duplicate properties and maintains consistent organization.

What are shorthand properties?

Shorthand properties combine multiple related properties into one line (e.g., margin: 10px vs. margin-top: 10px, margin-right: 10px, etc.). Expanding them can improve clarity.

Will formatting change my CSS behavior?

No, formatting only changes the appearance of the code, not its functionality. The tool includes syntax validation to ensure the CSS remains valid.
