A collection of useful Tailwind plugins from the team at Josephmark

• oklab
• containment

Oklab is a perceptual colourspace that is particularly good for gradients as it has a more uniform perceived lightness and hue compared to other colourspaces.

Using Oklab interpolation can make your CSS gradients a bit sweeter and more natural, however it's not supported in Firefox yet.

First, add oklab to your tailwind.config.js file:

// tailwind.config.js
const { oklab } = require("@josephmark/tailwind-plugins")
module.exports = {
  plugins: [oklab],
}

supports-oklab

Check for CSS support of Oklab colours

supports-oklab-grad

Check for CSS support of Oklab gradient interpolation

Note - all Oklab colour utilities currently allow JIT values only since your theme is probably in hex or RGB.

bg-gradient-oklab-to-[direction]

Use Oklab interpolation for gradients

eg: bg-gradient-oklab-to-r from-red-500 to-blue-500 or supports-oklab-grad:bg-gradient-oklab-to-r from-red-500 to-blue-500

Note: colours don't need to be Oklab to use interpolation

from-oklab-[colour]

Set gradient start to an Oklab colour

eg: from-oklab-[0.77_-0.09_-0.06] or supports-oklab:from-oklab-[0.77_-0.09_-0.06]

via-oklab-[colour]

Set gradient mid-point to an Oklab colour

eg: via-oklab-[0.78_0.06_0.16]

to-oklab-[colour]

Set gradient end to an Oklab colour

eg: to-oklab-[0.62_0.15_-0.16]

text-oklab-[colour]

Set text to an Oklab colour

eg: text-oklab-[0.77_-0.09_-0.06]

bg-oklab-[colour]

Set background to an Oklab colour

eg: bg-oklab-[0.77_-0.09_-0.06]

CSS containment can help with rendering optimisation, especially on long pages with lots of elements. Setting contain-content content-visibility-auto on an element will let the browser skip rendering it when it is offscreen, saving on render time.

First, add containment to your tailwind.config.js file:

// tailwind.config.js
const { containment } = require("@josephmark/tailwind-plugins")
module.exports = {
  plugins: [containment],
}

contain-[value]

Set the element's containment mode. Default values are available, and JIT values can be added for specific needs / combination values.

eg: contain-content or contain-[paint_layout]

content-visibility-[value]

Set the element's content visibility property.

eg: content-visibility-auto or content-visibility-hidden

contain-intrinsic-size

Set the element's contain-intrinsic-size property. This allows culled elements to contribute to the page's scroll height to minimise scrollbar jank.

eg: contain-intrinsic-size-auto or contain-intrinsic-size-[auto_500px]
