Plain Classes is a WordPress plugin that lets you type classes in Oxygen Builder Classic as plain text, instead of going through Oxygen’s selector system. It removes Oxygen’s limits on class names, so Tailwind-style classes such as md:, 2xl or w-[1/2] work, and it autocompletes classes from the framework you use.
Who Plain Classes Oxygen is for
- Oxygen Classic users who work with utility classes such as Tailwind (Winden).
- Developers who use Automatic.css or OxyMade in Oxygen.
- Anyone who wants to type and paste classes faster than Oxygen’s selector panel allows.
Plain Classes doesn’t add a CSS framework: it gives the framework you already use a faster class input in Oxygen Classic.
Fixed Oxygen Class name limitations
If you’ve ever needed to use Tailwind or any other framework that uses special characters, such as 2xl, md:, w-[1/2], or bg-[#123123], we have a solution for you. Once you activate plain classes, these limitations will be removed.

Frequently asked questions
Which frameworks does the autocomplete support?
Winden, Automatic.css, OxyMade and Oxygen’s own selector system. You get suggestions from the framework you use while you type in the class field.
Can I use Tailwind class names with special characters?
Yes. Oxygen normally rejects class names such as md:, 2xl, w-[1/2] or bg-[#123123]; with Plain Classes active, those limits are removed. For Tailwind in Oxygen, see Winden for Oxygen.
Does it leave empty CSS rules behind?
No. Plain classes bypass Oxygen’s selector system, so Oxygen doesn’t create an empty CSS rule for every class you add.
Does Plain Classes work with Oxygen 6?
No. Plain Classes is built for Oxygen Builder Classic. Oxygen 6 is a different editor: Classic is built with AngularJS and Oxygen 6 with Vue, so the add-on can’t simply be carried over. For Tailwind classes in Oxygen 6, see Winden for Oxygen 6.
Can I get a refund?
Yes. If you can’t get Plain Classes working, DPlugins refunds the full price within 14 days of the original purchase. The conditions are in the terms and conditions.
