Example
var fs = require('fs');
var postcss = require('postcss');
var pxtorem = require('postcss-pxtorem');
var css = fs.readFileSync('main.css', 'utf8');
var options = {
replace: false
};
var processedCss = postcss(pxtorem(options)).process(css).css;
fs.writeFile('main-rem.css', processedCss, function (err) {
if (err) {
throw err;
}
console.log('Rem file written.');
});
options
Type: Object | Null
Default:
{
divisor: 1,
multiple: 1,
decimalPlaces: 2,
comment: 'no',
targetUnits: 'rpx'
}
Detail:
- divisor(Number): divisor, replace pixel value with pixel / divisor.
- multiple(Number): multiple, replace pixel value with pixel * multiple.
- decimalPlaces(Number): the number of decimal places. For example, the css code is
width: 100px
, we will get the vaule isNumber(100 / divisor * multiple).toFixed(decimalPlaces)
. - comment(String): default value is 'no'. For example, if you set it 'not replace', the css code
width: 100px; /* not replace */
will be translated towidth: 100px;
- targetUnits(String): The units will replace pixel units, you can set it 'rem'.
Use with gulp-postcss
var gulp = require('gulp');
var postcss = require('gulp-postcss');
var pxtounits = require('postcss-pxtounits');
gulp.task('css', function () {
return gulp.src('./test/src/css/**/*.css')
.pipe(postcss([pxtounits()]))
.pipe(gulp.dest('./test/dist/css'));
});
