How to install Skeleton UI

To install Skeleton, we will use the Skeleton CLI for creating a new Skeleton project. This will automatically scaffold a new SvelteKit application, install Tailwind, configure Skeleton, and more. You can install it by running the following command in your terminal:

pnpm create skeleton-app@latest example-ui


  1. Skeleton app template
  2. Skeleton theme
  3. Add Popups
  4. TypeScript
  5. Optional

Create a basic UI with Skeleton

After installing Skeleton, you can create a basic UI by following these steps:

  1. Open your terminal and navigate to the project directory.
  2. Install the packages: pnpm install
  3. Open the file +page.svelte in your code editor.
  4. Add the following code to the file:
<script lang="ts">
    import { Autocomplete, popup, type AutocompleteOption, type PopupSettings } from "@skeletonlabs/skeleton";

    let input = '';
    const countryOptions: AutocompleteOption<string>[] = [
        { value: 'Argentina', label: 'Argentina' },
        { value: 'Bolivia', label: 'Bolivia' },
        { value: 'Brazil', label: 'Brazil' },

    function onCountrySelection(event: CustomEvent<AutocompleteOption<string>>): void {
        input = event.detail.label;

    let popupSettings: PopupSettings = {
        event: 'focus-click',
        target: 'popupAutocomplete',
        placement: 'bottom',

<div class="container card w-80 mx-auto p-4 my-16">
        class="input autocomplete"
    <div data-popup="popupAutocomplete" class="card w-72 max-h-48 p-4 overflow-y-auto">
  1. Save the file and run the following command in your terminal:
pnpm run dev
  1. Open your browser and navigate to http://localhost:5173. You should see a basic UI with an autocomplete search box.


In summary, Skeleton UI is a powerful UI toolkit built using Svelte and Tailwind CSS that allows you to create adaptive, accessible design systems for your web apps. To get started with Skeleton, use the Skeleton CLI for creating new projects. Once installed, you can easily create beautiful interfaces by following the steps outlined in this introduction to Skeleton UI.
