+# postcss-vw2rem 
+
+A plugin for [PostCSS](https://github.com/ai/postcss) that generates rem units from pixel units.
+
+This project is forked from [postcss-pxtorem](https://github.com/cuth/postcss-pxtorem) under the MIT license.
+
+## Why
+
+In some tablet or android fold devices, someone may think that arbitrarily scalling the size is inappropriate and that the size needs to be limited. `vw` is directly related to screen width, while `rem` can be restricted. 
+
+## Install
+
+```shell
+$ npm install postcss postcss-vw2rem --save-dev
+```
+
+## Usage
+
+Pixels are the easiest unit to use (*opinion*). The only issue with them is that they don't let browsers change the default font size of 16. This script converts every vw value to a rem from the properties you choose to allow the browser to set the font size.
+
+
+### Note
+
+`rootValue` below is set to `16`, so you can relate to the examples of `postcss-pxtorem`.
+
+While the default value is set to `10` in real project⚠️.
+
+### Input/Output
+
+*With the default settings, only font related properties are targeted.*
+
+```css
+// input
+h1 {
+    margin: 0 0 20vw;
+    font-size: 32vw;
+    line-height: 1.2;
+    letter-spacing: 1vw;
+}
+
+// output
+h1 {
+    margin: 0 0 20vw;
+    font-size: 2rem;
+    line-height: 1.2;
+    letter-spacing: 0.0625rem;
+}
+```
+
+### Example
+
+```js
+var fs = require('fs');
+var postcss = require('postcss');
+var vw2rem = require('postcss-vw2rem');
+var css = fs.readFileSync('main.css', 'utf8');
+var options = {
+    replace: false
+};
+var processedCss = postcss(vw2rem(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:
+```js
+{
+    rootValue: 16,
+    unitPrecision: 5,
+    propList: ['font', 'font-size', 'line-height', 'letter-spacing', 'word-spacing'],
+    selectorBlackList: [],
+    replace: true,
+    mediaQuery: false,
+    minPixelValue: 0,
+    exclude: /node_modules/i
+}
+```
+
+- `rootValue` (Number | Function) Represents the root element font size or returns the root element font size based on the [`input`](https://api.postcss.org/Input.html) parameter
+- `unitPrecision` (Number) The decimal numbers to allow the REM units to grow to.
+- `propList` (Array) The properties that can change from vw to rem.
+    - Values need to be exact matches.
+    - Use wildcard `*` to enable all properties. Example: `['*']`
+    - Use `*` at the start or end of a word. (`['*position*']` will match `background-position-y`)
+    - Use `!` to not match a property. Example: `['*', '!letter-spacing']`
+    - Combine the "not" prefix with the other prefixes. Example: `['*', '!font*']`
+- `selectorBlackList` (Array) The selectors to ignore and leave as vw.
+    - If value is string, it checks to see if selector contains the string.
+        - `['body']` will match `.body-class`
+    - If value is regexp, it checks to see if the selector matches the regexp.
+        - `[/^body$/]` will match `body` but not `.body`
+- `replace` (Boolean) Replaces rules containing rems instead of adding fallbacks.
+- `mediaQuery` (Boolean) Allow vw to be converted in media queries.
+- `minPixelValue` (Number) Set the minimum pixel value to replace.
+- `exclude` (String, Regexp, Function) The file path to ignore and leave as vw.
+    - If value is string, it checks to see if file path contains the string.
+        - `'exclude'` will match `\project\postcss-vw2rem\exclude\path`
+    - If value is regexp, it checks to see if file path matches the regexp.
+        - `/exclude/i` will match `\project\postcss-vw2rem\exclude\path`
+    - If value is function, you can use exclude function to return a true and the file will be ignored.
+        - the callback will pass the file path as  a parameter, it should returns a Boolean result.
+        - `function (file) { return file.indexOf('exclude') !== -1; }`
+- `unit` (String) Set the default unit to convert, default is `vw`.
+
+### Use with gulp-postcss and autoprefixer
+
+```js
+var gulp = require('gulp');
+var postcss = require('gulp-postcss');
+var autoprefixer = require('autoprefixer');
+var vw2rem = require('postcss-vw2rem');
+
+gulp.task('css', function () {
+
+    var processors = [
+        autoprefixer({
+            browsers: 'last 1 version'
+        }),
+        vw2rem({
+            replace: false
+        })
+    ];
+
+    return gulp.src(['build/css/**/*.css'])
+        .pipe(postcss(processors))
+        .pipe(gulp.dest('build/css'));
+});
+```
+
+### A message about ignoring properties
+Currently, the easiest way to have a single property ignored is to use a capital in the pixel unit declaration.
+
+```css
+// `vw` is converted to `rem`
+.convert {
+    font-size: 16vw; // converted to 1rem
+}
+
+// `Vx` or `VW` is ignored by `postcss-vw2rem` but still accepted by browsers
+.ignore {
+    border: 1vw solid; // ignored
+    border-width: 2vw; // ignored
+}
+```
