Tailwing Smart Fluid

Tailwind plugin that provides smart fluid spacing and typography using CSS clamp and viewport units.

This is currently experimental, and hasn't been fully tested. Use at your own risk

Installation

Install the plugin from npm:

Then add the plugin to your tailwind.config.js file:

Usage

This plugin uses Just In Time (JIT) to generate fluid version values for all spacing utilities.

In its simplest form, add the class fl-px-[20px,64px], where in this case 20px is the size at the minimum configured viewport (theme.fluid.min) and 64px is the size at the maximum configured viewport (theme.fluid.max).

You can also specify custom viewports, with fl-px-[20px@400px,64px@1440px]. In this example, when the screen is smaller than 400px the padding is 20px, when the screen is above 1440px it's 64px. Between these it will scale with the viewport width.

Notes:

• Values have to be provided with the same CSS unit; • If a unit is not specified, it will use px; • Breakpoints have to be provided with the same CSS unit; • Mixing units between values and breakpoints can produce unexpected results, especially mixing relative and absolute units. For this technique to work the plugin converts breakpoints to match the value unit which may not match what you'd expect.

Configuration

You can configure the default min and max viewport and whether the plugin should convert breakpoint units under the fluid key in your tailwind.config.js file:

Default config

| Property | Default | Notes |

| min | 576px | Minimum viewport when not specified | | max | 1024px | Maximum viewport when not specified | | convertUnits | true | Should the plugin try to convert breakpoint units | | rootFontSize | 16px | Base font-size for converting between rem and px | | custom | [] | Custom utilities to add in name: [properties] format |

Custom utilities

By default Tailwind Smart Fluid generates fluid versions of all default Tailwind spacing utilities.

It also adds a custom property that can be used for more complex situations—used with fl-var-[] and the --fluid-val property. This could be used within other property values or extended to other CSS functions.

If this doesn't meet your needs, you can also specify your own utilities in theme.fluid.extend:
