sheetify-custom-media
A sheetify transform to add support for
W3C-style CSS custom media queries
syntax. Uses rework-custom-media
to perform the transformation.
N.B. This is not a polyfill. This transform aims to provide a future-proof way of using a limited subset of the features provided by native CSS custom media queries.
Installation
npm install sheetify-custom-media
Usage
As a sheetify transform:
var media = require('sheetify-custom-media');
var sheetify = require('sheetify');
sheetify('path/to/my/index.css')
.transform(media())
.bundle();
Options
map
Optionally, you may define the for each in a JavaScript object that is passed to the function.
var myQueries = {
map: {
'--wide-screen': 'screen and (min-width:900px)'
}
}
variables({map: myQueries});
CSS syntax
A custom media query is defined with the @custom-media
rule. Its scope is
global.
@custom-media <extension-name> <media-query-list>;
The <extension-name>
can then be used in a media feature. The alias must be
wrapped in parentheses.
@custom-media --narrow-window screen and (max-width: 30em);
@media (--narrow-window) {
/* narrow window styles */
}
