@include('_partials.work-in-progress')

Add borders to any element using the .border{-side?}{-width?} syntax.

For example, .border would add a 1px border to all sides of the element, where .border-b-4 would add a 4px border to the bottom of the element.

Customizing

Responsive, Hover, and Focus Variants

By default, no hover, focus, or group-hover variants are generated for border width utilities.

You can control which variants are generated for the border width utilities by modifying the borderWidths property in the modules section of your Tailwind config file.

For example, this config will also generate hover and focus variants:

{
    // ...
    modules: { 
        // ...
        borderWidths: ['responsive', 'hover', 'focus'],
    }
}

Disabling

If you aren't using the border width utilities in your project, you can disable them entirely by setting the borderWidths property to false in the modules section of your config file:

{
    // ...
    modules: {
        // ...
        borderWidths: false,
    }
}
