Demo: Adding PostCSS plugins

- [Instructor] So let's do a demonstration now…of adding some PostCSS plug-ins.…So now that we have our own customized React scripts project…and we've been able to customize our PostCSS configuration…to allow stage zero features.…We also want to include some additional features…which are not included as part…of the PostCSS preset ENV package.…So what we're going to do is we're going to take a look…at how to actually add these additional plug-ins…both in terms of installing it with NPM…and then also registering it and we'll actually take a look…at how our CSS works for one of the functions…or one of the plug-ins, we'll take a look at how our code…doesn't work and then once we include that plug-in…you can actually then see how it does work,…and how we're actually adding features…and capabilities to our project.…

So what we're going to do is we're going to first…bring up the cssnext.io webpage.…So cssnext.io it actually lists all of the current features…that are part of what we call cssnext.…Now this, these features are actually distributed…
