.container {
  width: 100%;
  padding: 20px;
 @media (max-width: 768px) {

  @media (max-width: 480px) {

  }

2. Using Breakpoint Variables:
To improve maintainability and reduce repetition, define breakpoint values as variables.
Código

$breakpoint-mobile: 480px;
$breakpoint-tablet: 768px;

.container {
  width: 100%;
  padding: 20px;

  @media (max-width: $breakpoint-tablet) {
    padding: 10px;
  }
@media (max-width: $breakpoint-mobile) {padding: 5px; }}

3. Utilizing Mixins for Media Queries:
Mixins are a key feature in SCSS for creating reusable code blocks. You can define mixins for common media query breakpoints, encapsulating the @media rule and allowing you to include specific styles within them using @content.
	Código
	
@mixin for-phone-only {
  @media (max-width: 599px) {
    @content;
  } }

@mixin for-tablet-portrait-up {
  @media (min-width: 600px) {
    @content;
	}
}

.header {
  font-size: 26px;

  @include for-phone-only {
    font-size: 20px;
  }	@include for-tablet-portrait-up {
    font-size: 28px;
  }
}
