4、SASS - 注释 /* */ 与 //

Sass支持标准的css多行注释 /* */ ，以及单行注释 / / 

• /* */ 会出现在编译后的css文件中
• / /    不会出现在编译后的css文件

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. */
