methods

var insertPrefix = require('css-prefix')

insertPrefix(opts, src)

Insert the string opts.prefix before every class and id in the css source string src, returning the transformed source.

If opts.elementClass is given, add this class to all element identifiers. This is useful so that your h1 { color: green; } declarations don't leak into the environment.

If opts.parentClass is given, add an ancestor class to every rule.

If opts is a string, treat opts as opts.prefix.

install

With npm do:

npm install css-prefix
