Adding a nice syntax for handling media query breakpoints for different devices for rework

rework-breakpoints

NOTE Version v.0.5 uses min|max-width by default. To keep old behavior see Options below. Also the mixed syntax is new (see Example 5 below). NOTE Version v.0.6 uses screen instead of only screen by default. See Options below for how to keep old behavior.

Adding a nice syntax for handling media query breakpoints for different devices for the CSS Preprocessor rework.

npm install rework-breakpoints

An example of how to use rework-breakpoints:

var rework = require('rework'),
    breakpoints = require('rework-breakpoints');
 
var css = rework(cssString).use(breakpoints).toString();

Gives you a maintainable solution to handling media query breakpoints for different devices, with a syntax that's easy to remember.

A breakpoint is declared with: breakpoint-<name>: <type> <point> or breakpoint-<name>: <custom syntax>, where:

  • <name> - is the name for the breakpoint (to use in your media query)
  • <type> - values: min or max
  • <point> - the actual breakpoint value in px, em or rem
  • <custom syntax> - any breakpoint, e.g. screen and (orientation: landscape) and (max-width: 80em)

Note A breakpoint can be declared with var-breakpoint-<name> as well, for a valid CSS syntax.

Available options are:

If set the type/point syntax will generate media queries with min|max-device-width instead of the default min|max-width.

Set it in your CSS like so:

:root {
  breakpoints-device: true; /* `yes` or `1` works as well */
  /* OR */
  var-breakpoints-device: true;
}

If set the type/point syntax will generate media queries with only screen instead of the default screen.

Set it in your CSS like so:

:root {
  breakpoints-use-only: true; /* `yes` or `1` works as well */
  /* OR */
  var-breakpoints-use-only: true;
}
:root {
  breakpoint-mobile: max 340px;
}
 
@media mobile {
  /* all your mobile device styles goes here */
}

yields:

@media screen and (max-width: 340px) {
  /* styles... */
}
:root {
  breakpoints-use-only: true;
  breakpoint-mobile: max 340px;
}
 
@media mobile {
  /* all your mobile device styles goes here */
}

yields:

@media only screen and (max-width: 340px) {
  /* styles... */
}
:root {
  var-breakpoint-desk: min 80em;
}
 
@media desk {
  /* all your desktop styles goes here */
}

yields:

@media screen and (min-width: 80em) {
  /* styles... */
}
:root {
  breakpoints-device: yes;
  breakpoint-palm: max 340px;
  breakpoint-tab: max 700px;
  breakpoint-desk: min 1000px;
  breakpoint-desk-wide: min 1200px;
}
 
@media palm {
  /* all your palm device styles goes here */
}
@media tab {
  /* all tablet styles */
}
@media tab-and-down {
  /* styles for tablets and smaller devices */
}
@media tab-and-up {
  /* styles for tablets and bigger screens */
}
@media desk-and-down {
  /* styles for desktops and smaller devices */
}
@media desk-and-up {
  /* styles for desktop and bigger screens */
}
@media desk-wide {
  /* styles for big screens */
}

yields:

@media screen and (max-device-width: 340px) {
  /* styles... */
}
@media screen and (min-device-width: 341px) and (max-device-width: 700px) {
  /* all tablet styles */
}
@media screen and (max-device-width: 700px) {
  /* styles for tablets and smaller devices */
}
@media screen and (min-device-width: 341px) {
  /* styles for tablets and bigger screens */
}
@media screen and (max-device-width: 1199px) {
  /* styles for desktops and smaller devices */
}
@media screen and (min-device-width: 1000px) {
  /* styles for desktop and bigger screens */
}
@media screen and (min-device-width: 1200px) {
  /* styles for big screens */
}
:root {
  breakpoint-mobile: max 600px;
  breakpoint-landscape: (orientation: landscape);
}
 
@media mobile and landscape {
  body {
    color: #c00;
  }
}

yields:

@media screen and (max-width: 600px) and (orientation: landscape) {
  body {
    color: #c00;
  }
}

You get the point...
