Media Queries

We keep media queries fairly simple in Foundation and let the percentage-based grid do the heavy lifting across various screen sizes.

Basic

Media queries are built using ems in Foundation. At some point in time we will move to rem's, however, at the moment not all browsers like rem's in media queries.

CSS

// Small screens
@media only screen { } /* Define mobile styles */

@media only screen and (max-width: 40em) { } /* max-width 640px, mobile-only styles, use when QAing mobile issues */

// Medium screens
@media only screen and (min-width: 40.063em) { } /* min-width 641px, medium screens */

@media only screen and (min-width: 40.063em) and (max-width: 64em) { } /* min-width 641px and max-width 1024px, use when QAing tablet-only issues */

// Large screens
@media only screen and (min-width: 64.063em) { } /* min-width 1025px, large screens */

@media only screen and (min-width: 64.063em) and (max-width: 90em) { } /* min-width 1025px and max-width 1440px, use when QAing large screen-only issues */

// XLarge screens
@media only screen and (min-width: 90.063em) { } /* min-width 1441px, xlarge screens */

@media only screen and (min-width: 90.063em) and (max-width: 120em) { } /* min-width 1441px and max-width 1920px, use when QAing xlarge screen-only issues */

// XXLarge screens
@media only screen and (min-width: 120.063em) { } /* min-width 1921px, xxlarge screens */

Customize With Sass

Media queries can be easily customized by changing the variable values in _settings.scss.

SCSS

// Here we define the breakpoints which will become the upper border for each media size.
// The function em-calc() calculates the em-value from a px-value.
$small-breakpoint:  em-calc(640)  !default;
$medium-breakpoint: em-calc(1024) !default;
$large-breakpoint:  em-calc(1440) !default;
$xlarge-breakpoint: em-calc(1920) !default;

// Here we define the lower and upper bounds for each media size
$small-range:   (0, $small-breakpoint) !default; /* 0, 640px */
$medium-range:  ($small-breakpoint  + em-calc(1), $medium-breakpoint) !default; /* 641px, 1024px */
$large-range:   ($medium-breakpoint + em-calc(1), $large-breakpoint)  !default; /* 1025px, 1440px */
$xlarge-range:  ($large-breakpoint  + em-calc(1), $xlarge-breakpoint) !default; /* 1441px, 1920px */
$xxlarge-range: ($xlarge-breakpoint + em-calc(1), em-calc(99999999)) !default; /* 1921px, ... */

// Media Queries
$screen: "only screen" !default;

$landscape: "#{$screen} and (orientation: landscape)" !default;
$portrait: "#{$screen} and (orientation: portrait)" !default;

$small-up: $screen !default;
$small-only: "#{$screen} and (max-width: #{upper-bound($small-range)})" !default;

$medium-up: "#{$screen} and (min-width:#{lower-bound($medium-range)})" !default;
$medium-only: "#{$screen} and (min-width:#{lower-bound($medium-range)}) and (max-width:#{upper-bound($medium-range)})" !default;

$large-up: "#{$screen} and (min-width:#{lower-bound($large-range)})" !default;
$large-only: "#{$screen} and (min-width:#{lower-bound($large-range)}) and (max-width:#{upper-bound($large-range)})" !default;

$xlarge-up: "#{$screen} and (min-width:#{lower-bound($xlarge-range)})" !default;
$xlarge-only: "#{$screen} and (min-width:#{lower-bound($xlarge-range)}) and (max-width:#{upper-bound($xlarge-range)})" !default;

$xxlarge-up: "#{$screen} and (min-width:#{lower-bound($xxlarge-range)})" !default;
$xxlarge-only: "#{$screen} and (min-width:#{lower-bound($xxlarge-range)}) and (max-width:#{upper-bound($xxlarge-range)})" !default;

$retina: (
  "#{$screen} and (-webkit-min-device-pixel-ratio: 2)",
  "#{$screen} and (min--moz-device-pixel-ratio: 2)",
  "#{$screen} and (-o-min-device-pixel-ratio: 2/1)",
  "#{$screen} and (min-device-pixel-ratio: 2)",
  "#{$screen} and (min-resolution: 192dpi)",
  "#{$screen} and (min-resolution: 2dppx)"
);
