A PostCSS plugin that is used to wrap css styles with a css selector to constrain their affect on parent elements in a page.
Where do I start?
These instructions are only for this plugin, see PostCSS website for framework information.
1. Install the plugin.
npm install --save-dev postcss-prefixwrap
2. Add to your PostCSS configuration.
var gulp = require('gulp');
var postcss = require('gulp-postcss');
var prefixwrap = require("postcss-prefixwrap");
gulp.task("css", function () {
var processors = [
prefixwrap(".my-custom-wrap")
];
return gulp.src("./src/*.css")
.pipe(postcss(processors))
.pipe(gulp.dest("./dest"));
});
The above example is using Gulp.js, and is based on https://github.com/postcss/gulp-postcss README.md.
3. Add the container to your markup.
<div class="my-custom-wrap">
</div>
4. View your css, now prefix wrapped.
Before
p {
color: red;
}
body {
font-size: 16px;
}
After
.my-custom-wrap p {
color: red;
}
.my-custom-wrap {
font-size: 16px;
}
