Manual:Coding conventions/LESS

Whitespace

 * One selector per line
 * Opening braces for the declaration block or sub-block on the same line as the (last) selector
 * Indent each declaration with a tab, with additional indents for sub-blocks (e.g. descendants).
 * No space before the colon
 * 1 space between the colon and the value
 * a semi-colon after each declaration (including the last one)
 * Closing braces unindented back to the left
 * noflip annotation for CSSJanus and CSSMin should be on their own line, above the LESS rule they're for. Embed should call embed mixin.
 * An empty line between one LESS rule set and the next.
