The Way We Do It Now

Media queries are grouped with each module/element/selector. Have to repeat the properties in each MQ, and often write a MQ just to declare the one property that will change.

@tablet: 768px;
@desktop-sm: 992px;
@desktop-lg: 1200px;
  
.hero-main-heading {
  position: absolute;
  top: 20px;
  left: 0;
  color: #fff;
  margin-top: 20px;
  margin-bottom: 40px;
  width: 100%;
  display: none;
  @media (min-width: @tablet) {
    display: block;
    position: absolute;
    max-width: 85%;
    bottom: 340px;
    left: 145px;
    top: auto;
  }
  @media (min-width: @desktop-sm) { bottom: 280px; }
  @media (min-width: @desktop-lg) { bottom: 360px; }
}

A New Proposed Syntax

Each CSS property can have an object with a set of media query / value pairs. In this example, media queries are expressed as variables. Still cumbersome to write the variables every time.

.hero-main-heading {
  position: absolute;
  top: 20px;
  left: 0;
  color: #fff;
  margin-top: 20px, {
    @tablet: 40px,
    @desktop-sm: 340px
  };
  margin-bottom: 40px;
  width: 100%;
  display: none, {
    @tablet: block
  };

  bottom: auto, {
    @tablet: 50px,
    @desktop-sm: 340px,
    @desktop-lg: 360px
  };
}

A Shorthand Version of the New Syntax

Each CSS property can have an object with a set of media query / value pairs, but the order determines which media query each value corresponds to, rather than having to write them each time.

+mediaSetting = min-width;
+mediaQueries = { @tablet, @desktop-sm, @desktop-lg };

.hero-main-heading {
  position: absolute;
  top: 20px;
  left: 0;
  color: #fff;
  margin-top: 20px, { 40px, 340px };
  margin-bottom: 40px;
  width: 100%;
  display: none, { block };
  bottom: auto, { 50px, 340px, 360px };
}
