Single-Line Format for Simple Declarations
For selectors with only one or two simple declarations, using a single-line format can reduce visual clutter and make the code more concise. This approach is particularly useful for large blocks of declarations that don not require complex formatting.
In this format the opening brace { is followed by the property and value on the same line. A space is added before the closing brace } for improved readability. This style works well for concise rules where the selector and declaration are short, keeping the stylesheet clean and manageable.
Multi-Line Format for Complex Values
When dealing with long, comma-separated property values, such as collections of gradients or shadows, a multi-line format can greatly improve readability. By splitting these values across multiple lines, the code becomes easier to read, debug, and maintain. It also makes version control diffs more useful, as individual changes are more apparent.
In this format each value is placed on a new line and indented for clarity. The properties are still grouped logically, but the multi-line structure ensures that long values are readable and modifications are easier to track.
