include-media: Simple, elegant and maintainable media queries in Sass

I’ve just converted my Sass code to use this, and I can safely say it’s pretty excellent.

include-media is a Sass library for writing CSS media queries in an easy and maintainable way, using a natural and simplistic syntax.

[…]

Why another library?

I spent quite some time experimenting with different libraries and mixins available out there, but eventually all of them failed to do everything I needed in an elegant way. Some of them wouldn’t let me mix set breakpoints with case-specific values, others wouldn’t properly handle the CSS OR operator and most of them had a syntax that I found complicated and unnatural.

include-media was the result of that experience and it includes all the features I wish I had found before, whilst maintaining a simplistic and natural syntax.

I wrote an article on CSS-Tricks about this experience, where I explain in detail the problems I found with each of the solutions I experimented with. I also wrote on David Walsh’s blog about the implementation details of include-media.

Example usage:

Sass

$breakpoints: (small: 320px, medium: 768px, large: 1024px);
 
/* Inclusive and exclusive operators for a finer control over the intervals */
@include media(">medium", "<=large") {
	width: 100%;
}

Easing Linear Gradients

Linear gradients are easy to create in CSS and are extremely useful. As we’ll go through in this article, we can make them visually much smoother by creating them with non-linear gradients. Well, non-linear in the easing sense, anyway!

[…]

In Material Design style guidelines for images, the designers at Google talk about text protection gradients. They call them a scrim. They recommend:

[the] gradient should be long… with the center point about 3/10 towards the darker side of the gradient. This gives the gradient a natural falloff and avoids a sharp edge.

A scrim according to Material Design guidelines

We can’t create exactly that with linear gradients, but we can (and will) create a “low poly” approximation with more color stops.

A scrim with 5 color stops to show the principle

Using only 5 color stops (like in the illustration above) would create some serious banding. Adding more stops makes the gradient a lot smoother. This is exactly what I’ve done in the demo you saw in the first image in this article. Il buono has a 13 color-stop gradient, which makes it blend nicer into the image.

Fluid Type on CodePen Blogs

It became more popular to “go fully responsive” with layouts, where widths were largely in percentages, so that you get to use as much room is available at any given screen size. To a point, anyway.

You can also “go fully responsive” with typography, in a sense. There are a number of Pens by Mike Riethmuller that tackle things like fluid type size, fluid modular scale, and even fluid vertical rhythm.

It’s worth reading up on Mike’s technique here, but a distilled Sass version is like:

Sass

@function strip-unit($value) {
  @return $value / ($value * 0 + 1);
}
 
@mixin fluid-type($min-vw, $max-vw, $min-font-size, $max-font-size) {
  $u1: unit($min-vw);
  $u2: unit($max-vw);
  $u3: unit($min-font-size);
  $u4: unit($max-font-size);
 
  @if $u1 == $u2 and $u1 == $u3 and $u1 == $u4 {
    & {
 
      font-size: $min-font-size;
      @media screen and (min-width: $min-vw) {
        font-size: calc(#{$min-font-size} + #{strip-unit($max-font-size - $min-font-size)} * ((100vw - #{$min-vw}) / #{strip-unit($max-vw - $min-vw)}));
      }
 
      @media screen and (min-width: $max-vw) {
        font-size: $max-font-size;
      }
    }
  }
}
 
$min_width: 320px;
$max_width: 1200px;
$min_font: 16px;
$max_font: 24px;
 
$mod_1: 1.2; // mobile
$mod_2: 1.5; // desktop
 
html {
  @include fluid-type($min_width, $max_width, $min_font, $max_font);
}
 
h1 {  
  font-size: $mod_1*$mod_1*$mod_1*$mod_1 *1rem; 
  @include fluid-type($min_width, $max_width, $mod_1*$mod_1*$mod_1 *$min_font, $mod_2*$mod_2*$mod_2 *$min_font);
}
h2 {  
  font-size: $mod_1*$mod_1*$mod_1 *1rem; 
  @include fluid-type($min_width, $max_width, $mod_1*$mod_1*$mod_1 *$min_font, $mod_2*$mod_2*$mod_2 *$min_font);
}
h3 { 
  font-size: $mod_1*$mod_1 *1rem;
  @include fluid-type($min_width, $max_width, $mod_1*$mod_1 *$min_font, $mod_2*$mod_2 *$min_font);
}
