How to Create Custom Gradients in Tailwind CSS with JIT

What is JIT?

Since v3, JIT has been the default in Tailwind CSS and has bought a lot of power to the framework. One of the best additions are arbitrary values, these allow you to replace custom CSS with Tailwind CSS like classes.

Without Tailwind CSS JIT

<div class="floating-alert absolute p-4">Hello World! 👋</div>

And for the CSS...

.floating-alert {
  bottom: 5px;
  right: 5px;
}

With Tailwind CSS JIT

<div class="absolute bottom-[5px] right-[5px] p-4">Hello World! 👋</div>

The benefit here is keeping everything within the HTML, this means:

  • Less switching between files
  • No need to update Tailwind CSS config
  • Easily use Tailwind CSS breakpoints top-[2px] sm:top-[3px] lg:top-[5px]

Creating Gradients with Tailwind CSS JIT

If you are using these gradients more than once, it's worth adding them to the Tailwind CSS config.

The syntax for creating a gradient looks confusing, but it's easy to understand once you realise that spaces are replaced with underscores. Take the following example:

In CSS this would be:

background-image: linear-gradient(180deg, #eab308 40%, #a855f7 60%, #3b82f6);

The underscores after commas are personal choice, I leave them in for readability but you can remove them.

Conic Gradients in Tailwind CSS with JIT

For this I've used Hypercolor to find a conic-gradient for the example.

Here's a preview of how that looks:

Which results in the follow CSS:

background-image: conic-gradient(at left center, #eab308, #a855f7, #3b82f6);

Radial Gradients in Tailwind CSS with JIT

Once again I'm using Hypercolor to find a radial-gradient for the example.

Here's a preview of how that looks:

Which results in the follow CSS:

background-image: radial-gradient(at center bottom, #fde68a, #7c3aed, #0c4a6e);
