tailwindcss-fluid-text v2.0.7

👉🏻 tailwindcss-fluid-type

A plugin that makes the use of Fluid Type a breeze.

👉🏻 Installation

Install the plugin from npm:

# Using npm
npm install tailwindcss-fluid-type

# Using Yarn
yarn add tailwindcss-fluid-type

Then add the plugin to your tailwind.config.js file and do your settings if you're not happy with the defaults:

// tailwind.config.js
module.exports = {
    // You can disable the fontSize core plugin if you don't need non fluid font sizes. 
    // If you don't disable it, the fluid-type plugin simply overrule the default font-sizes if the keys are the same.
    // Or you can use both alongside when you set an prefix in the settings
    corePlugins: {
        fontSize: false,
        // ...
    },
    plugins: [
        require('tailwindcss-fluid-type'),
        // ...
    ],
};

👉🏻 Usage

Nothing changed here to the default tailwindcss configuration:

<article>
    <h1 class="text-xl">Fluid type</h1>
</article>

👉🏻 Configuration

The plugin comes with a default configuration (see below) but it's possible to customize this config for your project. As default, we use rem for better accessibility, but you can also use px.

Important Note:

If you set values you have to set all values that you need for your font-sizes. There is no value merging here.

Default configuration

// tailwind.config.js
module.exports = {
    plugins: [
        require('tailwindcss-fluid-type')({
            // your fluid type settings
            // works only with unitless numbers
            // This numbers are the defaults settings
            settings: {
                fontSizeMin: 1.125, // 1.125rem === 18px
                fontSizeMax: 1.25, // 1.25rem === 20px
                ratioMin: 1.125, // Multiplicator Min
                ratioMax: 1.2, // Multiplicator Max
                screenMin: 20, // 20rem === 320px
                screenMax: 96, // 96rem === 1536px
                unit: 'rem', // default is rem but it's also possible to use 'px'
                prefix: '', // set a prefix to use it alongside the default font sizes
                extendValues: true, // When you set extendValues to true it will extend the default values. Set it to false to overwrite the values.
            },
            // Creates the text-xx classes
            // This are the default settings and analog to the tailwindcss defaults
            // Each `lineHeight` is set unitless and we think that's the way to go especially in context with fluid type.
            values: {
                'xs': [-2, 1.6],
                'sm': [-1, 1.6],
                'base': [0, 1.6],
                'lg': [1, 1.6],
                'xl': [2, 1.2],
                '2xl': [3, 1.2],
                '3xl': [4, 1.2],
                '4xl': [5, 1.1],
                '5xl': [6, 1.1],
                '6xl': [7, 1.1],
                '7xl': [8, 1],
                '8xl': [9, 1],
                '9xl': [10, 1],
            },
        }),
    ],
    variants: {
        fluidType: ['responsive']
    }
};

Fluid type configuration without lineHeight

It is also possible to set just the fontSize without set the lineHeight

// tailwind.config.js
module.exports = {
    plugins: [
        require('tailwindcss-fluid-type')({
            values: {
                // ...
                'base': 0,
                // ...
            }
        }),
    ]
};

Fluid type configuration with lineHeight & letterSpacing

And yes, you can also set the letterSpacing & lineHeight as you know from the tailwind documentation. letterSpacing can be all values that you like.

// tailwind.config.js
module.exports = {
    plugins: [
        require('tailwindcss-fluid-type')({
            values: {
                // ...
                'base': [0,
                    {
                        lineHeight: 1.6,
                        letterSpacing: '-0.1rem',
                    }
                ],
                // ...
            }
        }),
    ]
};

👉🏻 Samples

Just set the fontSize property

// tailwind.config.js
module.exports = {
    plugins: [
        require('tailwindcss-fluid-type')({
            settings: {
                fontSizeMin: 1.125,
                fontSizeMax: 1.25,
                ratioMin: 1.125,
                ratioMax: 1.2,
                screenMin: 20,
                screenMax: 96,
                unit: 'rem',
                prefix: ''
            },
            values: {
                // ...
                'base': 0,
                // ...
            }
        }),
    ]
};

<p class="text-base">The quick brown fox jumps over the lazy dogs</p>

.text-base {
    font-size: clamp(1.125rem, calc(1.125rem + (1.25 - 1.125) * ((100vw - 20rem) / (96 - 20))), 1.25rem);
}

Set the fontSize & lineHeight property

// tailwind.config.js

                // ...
            }
        }),
    ]
};

<p class="text-base">The quick brown fox jumps over the lazy dogs</p>

.text-base {
    font-size: clamp(1.125rem, calc(1.125rem + (1.25 - 1.125) * ((100vw - 20rem) / (96 - 20))), 1.25rem);
    line-height: 1.6;
}

Set the fontSize, lineHeight & letterSpacing property

// tailwind.config.js
module.exports = {
    plugins: [
