tailwindcss-inner-border

A plugin that provides utilities for creating inner borders with box-shadow.

Installation

Install the plugin from npm:

npm install -D tailwindcss-inner-border

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

// tailwind.config.js
module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require("tailwindcss-inner-border"),
    // ...
  ],
};

Usage

Use the inner-border-{n} utilities to set the inner border width for all sides of an element:

<input class="inner-border ...">
<input class="inner-border-2 ...">

Control the inner border color of an element using the inner-border-{color} utilities:

<input class="inner-border-2 inner-border-rose-500 ...">

Variants and color opacity modifiers may also be used:

<input class="inner-border-2 inner-border-rose-500/75 hover:inner-border-rose-500 ...">

Configuration

You can configure which values and variants are generated by this plugin under the borderWidth and borderColor keys in your tailwind.config.js file.

Note

By default, Tailwind makes the entire default color palette available as border colors. You can customize your color palette by editing theme.colors or theme.extend.colors as shown below.

// tailwind.config.js
module.exports = {
  theme: {
    borderWidth: {
      DEFAULT: "1px",
      0: "0px",
      2: "2px",
+     3: "3px",
      4: "4px",
+     6: "6px",
-     8: "8px",
    },
    extend: {
+     colors: {
+       "regal-blue": "#243c5a",
+     },
    },
  },
};
