    To control the border color of an element at a specific breakpoint, add a {screen}: prefix to any existing border color utility. For example, use md:border-green-500 to apply the border-green-500 utility at only medium screen sizes and above.

    Hover

    To control the border color of an element on hover, add the hover: prefix to any existing border color utility. For example, use hover:border-blue-500 to apply the border-blue-500 utility on hover.

    Hover utilities can also be combined with responsive utilities by adding the responsive {screen}: prefix before the focus: prefix.

    To control the border color of an element on focus, add the focus: prefix to any existing border color utility. For example, use focus:border-blue-500 to apply the border-blue-500 utility on focus.

    1. <input class="border-gray-400 focus:border-blue-500 ...">

    Focus utilities can also be combined with responsive utilities by adding the responsive {screen}: prefix before the focus: prefix.

    Customizing

    By default Tailwind makes the entire available as border colors.

    You can customize your color palette by editing the theme.colors section of your tailwind.config.js file, or customize just your border colors using the theme.borderColor section.

    1.   // tailwind.config.js
    2.   module.exports = {
    3.     theme: {
    4.       borderColor: theme => ({
    5. -       ...theme('colors'),
    6. +       'primary': '#3490dc',
    7. +       'secondary': '#ffed4a',
    9.       })
    10.     }
    11.   }

    By default, only responsive, hover and focus variants are generated for border color utilities.

    You can control which variants are generated for the border color utilities by modifying the borderColor property in the variants section of your tailwind.config.js file.

    For example, this config will also generate active and group-hover variants:

    1.   // tailwind.config.js
    2.   module.exports = {
    3.     variants: {
    4.       // ...
    5. -     borderColor: ['responsive', 'hover', 'focus'],
    6. +     borderColor: ['responsive', 'hover', 'focus', 'active', 'group-hover'],
    7.   }
