Sass支持标准的css多行注释 /* */ ，以及单行注释 / /
例如：
/* This comment is * several lines long. * since it uses the CSS comment Syntax,* it will appear in the CSS output. */ body { color: black; } // These comments are only one line long each. // They won‘t appear in the CSS output,// since they use the single-line comment Syntax. a { color: green; }
编译为：
/* This comment is * several lines long. * since it uses the CSS comment Syntax,* it will appear in the CSS output. */ body { color: black; } a { color: green; }
插值语句 #（变量） ============ #（$version：“1.2.3”）；可以在多行注释中输出变量值。例如：
$version: "1.2.3"; /* This CSS is generated by My Snazzy Framework version #{$version}. */
编译为：
/* This CSS is generated by My Snazzy Framework version 1.2.3. */
