How Can I Use `@import` in an `@if` Statement in Sass for Conditional CSS Loading?

@import in @if Statement in Sass: Handling Conditional CSS Loading

In the context of Sass, you may encounter situations where you want to conditionally load specific CSS based on определённые условия. One approach is to use the @import directive within an @if statement. However, this approach is not supported in Sass.

The error message, "Import directives may not be used within control directives or mixins," indicates that using @import directly in an @if statement is not allowed. This restriction exists because @import is a directive that processes imports before the compilation process, while @if is a control directive that evaluates conditions.

To workaround this limitation, you can use mixins to achieve conditional CSS loading. Here's a possible solution:

partial.scss

<code class="scss">@mixin partial {
  // Styles for the partial mixin go here
}</code>

styles.scss

<code class="scss">@import "partial"; // Import the partial mixin

@if $someval == true {
  @include partial; // Call the mixin when the condition is met
}</code>

In this revised approach, the @import directive is moved outside the @if statement, importing the partial mixin file. Then, within the @if statement, you can call the partial mixin when the condition is met. This allows you to conditionally include the styles from the partial mixin into your compiled CSS output.
