Classes including : not at the beginning are not extracted

Hey there, I’m currently using Tailwind CSS which is a utility class library. It uses classes that look like .md:w-1/3 which contains a semicolon :. It doesn’t look like PurgeCSS will extract classes like this properly.

PurifyCSS doesn’t do this right either but has a fork called purifycss-extended which does a pretty good job at it.

Do you think this is something that can be supported in PurgeCSS?

Thank you!

Thanks @andrewdelprete, your help is welcome. I investigated the problem. The selectors were not unescaped by purgecss. Purgecss compared md:w-2/3 to md\:w-2\/3 and did not match it.

I fixed the issue and publish a new version of purgecss and the webpack plugin. I also updated the webpack example here to show how it can be used with custom extractors.

Let me know if you are still experiencing the issue.
