The effectiveness of Tailwind utility classes is exclusive to CSS files rather than inline code

My tech stack includes electron, react (web), typescript, and tailwind. Currently, I am encountering an issue where tailwind only applies styles in .css files but not inline. See the example below:

In .css file (works)

.navbar {
    @apply border-2 border-red-900;
}

In .tsx file

<div className="navbar">
    </div>

Just in .tsx (does not work)

<div className="border-2 border-red-900">
</div>

Despite having the content defined correctly in my tailwind.config.js:

module.exports = {
  mode: "jit",
  content: ["./src/**/*.{js, jsx, ts, tsx}", "./public/index.html"],
  darkMode: false, // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
};

During compilation, I receive a warning stating:

no utility classes were detected in your source files. If this is unexpected, double-check the content option in your Tailwind CSS configuration

The index.css includes the following:

@tailwind base;
@tailwind components;
@tailwind utilities;

Answer №1

By adhering to the guidelines outlined in content configuration, you can ensure efficient usage of Tailwind.

Tailwind CSS operates by analyzing your HTML, JavaScript components, and template files for class names, then producing corresponding CSS styles.

To enable Tailwind to generate the necessary CSS, it must be aware of all project files containing Tailwind class names.

  • Utilize * to match everything except slashes and hidden files
  • Employ ** to match any number of directories
  • Use comma-separated values within {} to match against a selection of options

If you suspect that your content config path is incorrect, verify the path to guarantee proper scanning of all source files with Tailwind class names.

Answer №2

To include this in your public/index.html file:

<script src="https://cdn.tailwindcss.com"></script>
