function-calc-no-unspaced-operator

禁止 数学函数 中的无效无空格运算符，例如 calc() 或 min()。

¥Disallow invalid unspaced operator within math functions, such as calc() or min().

a { top: calc(1px + 2px); }
/**               ↑

 * The space around this operator */

此规则检查 + 或 - 运算符之前是否有单个空格或换行符加缩进，以及该运算符之后是否有单个空格或换行符。

¥This rule checks that there is a single whitespace or a newline plus indentation before the + or - operator, and a single whitespace or a newline after that operator.

fix 选项 可以自动修复此规则报告的所有问题。
