The complexity of a condition is defined by the number of `and` and `or` operators.

A single condition's complexity should not become too high to keep the code readable.

## Noncompliant Code Example

With a maximum allowed number of conditional operators of 3:

    @if $height < 10 px and $width < 20px and $depth < 5px or $is-box-valid {
      do-something();
    }

## Compliant Solution

With a maximum allowed number of conditional operators of 3:

    $is-box-small-enough: $height < 10 px and $width < 20px and $depth < 5px;

    @if $is-frame-small-enough or $is-box-valid {
      do-something();
    }
