There are a lot of great frameworks for Oxygen out there such as Automatic.css, OxyNinja, and OxyMade. In this article, we're going to go over Tailwind CSS, which is a framework that is a utility-first CSS framework that only loads the necessary CSS from its framework onto your site. This is slightly different from the other frameworks above that load all their classes and stylesheets into Oxygen, which means their entire framework is loaded onto your site.

Now, there are at least two quick-start ways to get Tailwind CSS working with Oxygen. The first is through a plugin called Oxywind, which has a yearly cost and is designed specifically for Oxygen. The second is through a plugin called TailPress, which is free (at least at the time of this writing).

We're going to use TailPress in this example.

Basic Setup:

To get started with Tailwind CSS, you'll need to do the following:

1. Go to Plugins > Add New in /wp-admin and search for "TailPress". Once you've found the plugin, install it and activate it.
2. Next, go to https://tailwindcss.com, and keep that tab open as you'll want to reference it for class names.

That's it for the basic setup, we can now get started designing with Tailwind CSS.

Designing a Site in Oxygen:

Now that Tailwind CSS is all set, we can get started on designing. You can do this by opening a page or template in Oxygen.

Once you have a page or template open, go ahead and start adding some classes to an element. For example, to make a Section black, you can add the class "bg-black" to the Section.

You can use other colors with different shades as well, such as "bg-indigo-700" or "bg-indigo-400".

Or, you can use "text-center" to center-align the text within a section, and you can use "text-white" to make the font color white. And you can change the font size by using something such as "text-2xl" or "text-4xl".

As long as the class is available in Tailwind CSS, you'll see the changes take place immediately in Oxygen and on the front end.

The one caveat to the TailPress integration with Oxygen is that each class will be added twice to the stylesheet. The first time, the class is added by Oxygen and will contain a blank CSS declaration. The second time, the class is added by TailPress with the necessary rules for the declaration. So, this does create a small amount of bloat on your site. I don't know how/if Oxywind handles this in their plugin.

Modifying your Tailwind Config

TailPress does allow you to modify your Tailwind Config via Settings > TailPress in /wp-admin. So, for example, you can add custom colors using something such as the following:

{
	corePlugins: {
		preflight: false,
	},
	theme: {
		colors: {
			'primary':'#223543',
			'secondary':'#ca9d76',
			'accent':'#dcd9c1',
			'base':'#5d5d52',
			'shade':'#73724a',
		}
	}
}

You can then call those colors in Oxygen using classes such as "text-primary" or "bg-color-primary". This is great when you want to keep your colors subjective to their use and allow for easy color updating based on holidays or dark themes.

There are more options you can add to your configuration that you can read about here: https://tailwindcss.com/docs/theme.

That's it for this tutorial, happy sailing!
