Tailwind CSS Svelte - Flowbite

Learn how to install Tailwind CSS with Flowbite for your Svelte project and start developing modern web applications using interactive elements based on utility classes

Svelte is a modern and growing front-end compiler. Developers build boilerplate-free components using languages HTML, CSS and JavaScript. Svelte compiles your code to tiny, framework-less vanilla JS.

Install SvelteKit and Tailwind CSS #

Before anything make sure that you install SvelteKit and Tailwind CSS. If you already have them installed, you can proceed to the next step.

npm init svelte@next sveltekit-demo
cd sveltekit-demo

npm install
npx svelte-add@latest tailwindcss

Method 1: Using Flowbite-Svelte #

Flowbite Svelte is an official Flowbite component library for Svelte. All interactivities are handled by Svelte.

Install Flowbite-Svelte using NPM:

npm i -D flowbite-svelte

Update the tailwind.config.js file with the following details:

const config = {
  content: [
    "./src/**/*.{html,js,svelte,ts}",
    "./node_modules/flowbite-svelte/**/*.{html,js,svelte,ts}",
  ],

  theme: {
    extend: {},
  },

  plugins: [
    require('flowbite/plugin')
  ],
  darkMode: 'class',
};

module.exports = config;

Method 2: Using Flowbite.js #

If you prefer using flowbite.js, after installing Tailwind CSS, install flowbite:

npm i -D flowbite

Update tailwind.config.js by adding the following:

plugins: [
    require('flowbite/plugin')
  ],

Update src/__layout.svelte by adding flowbite.css:

<script>
  import "../app.css";
  import "flowbite/dist/flowbite.css";
</script>

Modify the src/app.html by adding flowbite.js as the following:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="description" content="" />
    <link rel="icon" href="%svelte.assets%/favicon.png" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
	%svelte.head%
    </head>
  <body>
    <div id="svelte">%svelte.body%</div>
    <script src="https://unpkg.com/flowbite@1.5.4/dist/flowbite.js"></script>
  </body>
</html>

Method 3 Using CDN #

This method uses the CDN and using Flowbite unpurged CDN JS/CSS. You don’t need to install TailwindCSS nor Flowbite. The Flowbite contains Tailwind CSS v3.0.1. So you can add CSS and JS link in the src/app.html. Place flowbite.min.css in the head and flowbite.js just before the body tag.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="description" content="" />
    <link rel="icon" href="%svelte.assets%/favicon.png" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <link rel="stylesheet" href="https://unpkg.com/@themesberg/flowbite@1.3.0/dist/flowbite.min.css" />
  %svelte.head%
  </head>
  <body>
    <div id="svelte">%svelte.body%</div>
   <script src="https://unpkg.com/flowbite@1.5.4/dist/flowbite.js"></script>
  </body>
</html>

If you want it only in a certain directories, create src/your-dir/__layout.svelte and add the Flowbite CSS in the svelte:head section.

<svelte:head>
<link rel="stylesheet" href="https://unpkg.com/flowbite@1.3.2/dist/flowbite.min.css" /></svelte:head> 
<slot />

If you are using Flowbite.js, you need to add rel="external" to the link tag for pages using Flowbite interactivities.

<a rel="external" href="path">Path</a>

By default, the SvelteKit runtime intercepts clicks on <a> elements and bypasses the normal browser navigation for relative (same-origin) URLs that match one of your page routes. — SvelteKit doc Adding a rel=external attribute to a link will trigger a browser navigation when the link is clicked.
