I'm taking a wild guess here, but I suspect there are many people who need that entry level/internship opportunity to cement some concepts while working on a team.

The problem is, like the rest of America, junior positions seem to have vanished. At least on job boards and hiring pages.

Can anyone point us to a good resource to find junior positions or even internships in front-end coding or UX design?

I'm not asking for any company to completely teach me stuff. The ideal position would require a portfolio but maybe one that isn't completely cross-browser, production-quality code.
