(if you're building +// your own skin this may not apply) +// 1. Comments inside of rules (strangely) have an extra line added after +// them in the CSS output. To avoid this we can add a LESS comment after +// the CSS comment. +// /* comment */// +// +// 2. In a rule with nested rules, any comments outside of a rule are moved +// to the top of the parent rule. i.e. it might look like: +// /* title of rule 1 */ +// /* title of rule 2 */ +// .rule1 {} +//
