Show dev: I built a collection of popover components with Tailwind CSS

Hello devs

Me and my friends built a collection of popover components using the utility-first Tailwind CSS framework classes and building a JavaScript integration with the Flowbite component library.

A popover is basically a popup-box that shows when hovering or clicking over a trigger element where you can show additional information like a paragraph, user profile info, and more.

Here's a preview of one of the popover components:

In this article I will show you the collection of popover examples and how you can get started using them in your projects.

Getting started

First of all, you need to make sure that you have Tailwind CSS and Flowbite installed in your project.

Install Tailwind CSS

You can either follow the quickstart guide or follow the next steps to install Tailwind CSS:

Install tailwindcss via NPM:

npm install -D tailwindcssnpx tailwindcss init

Configure the template paths inside the tailwind.config.js file:

/** @type {import('tailwindcss').Config} */ module.exports = {  content: ["./src/**/*.{html,js}"],  theme: {    extend: {},  },  plugins: [],}

Create a new src/input.css file and add the following content:

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

Compile and watch for changes in CSS:

npx tailwindcss -i ./src/input.css -o ./dist/output.css --watch

Great! Now that you have Tailwind CSS installed we can proceed by installing Flowbite as well.

Install Flowbite

Install Flowbite as a dependency using NPM by running the following command:

npm i flowbite

Require Flowbite as a plugin inside the tailwind.config.js file:

module.exports = {    plugins: [        require('flowbite/plugin')    ]}

Include the main JavaScript file to make interactive elements work:

<script src="../path/to/flowbite/dist/flowbite.js"></script>

Additionally to your own content data you should add flowbite to apply the classes from the interactive elements in the tailwind.config.js file:

module.exports = {    content: [        "./node_modules/flowbite/**/*.js"    ]}

If you use Webpack or other bundlers you can also import it like this:

import 'flowbite';

Include via CDN

The quickest way to get started working with FlowBite is to simply include the CSS and JavaScript into your project via CDN.

Require the following minified stylesheet inside the head tag:

<link rel="stylesheet" href="https://unpkg.com/flowbite@{{< current_version >}}/dist/flowbite.min.css" />

And include the following JavaScript file before the end of the body element:

<script src="https://unpkg.com/flowbite@{{< current_version >}}/dist/flowbite.js"></script>

Awesome! Now that you have both Tailwind CSS and Flowbite installed in your project you can use the Popover component collection right away.

Tailwind CSS Popover

Initialize a new popover by adding the data-popover-target="{elementId}" data attribute to the trigger element where elementId is the id of the popover component.

Source code:

<button data-popover-target="popover-default" type="button" class="text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:outline-none focus:ring-blue-300 font-medium rounded-lg text-sm px-5 py-2.5 text-center dark:bg-blue-600 dark:hover:bg-blue-700 dark:focus:ring-blue-800">Default popover</button><div id="popover-default" role="tooltip" class="inline-block absolute invisible z-10 w-64 text-sm font-light text-gray-500 bg-white rounded-lg border border-gray-200 shadow-sm opacity-0 transition-opacity duration-300 dark:text-gray-400 dark:border-gray-600 dark:bg-gray-800">    <div class="py-2 px-3 bg-gray-100 rounded-t-lg border-b border-gray-200 dark:border-gray-600 dark:bg-gray-700">        <h3 class="font-semibold text-gray-900 dark:text-white">Popover title</h3>    </div>    <div class="py-2 px-3">        <p>And here's some amazing content. It's very engaging. Right?</p>    </div>    <div data-popper-arrow></div></div>

Here's another example where you can use information about a user profile instead of a description:

Source code:

<button data-popover-target="popover-user-profile" type="button" class="text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:outline-none focus:ring-blue-300 font-medium rounded-lg text-sm px-5 py-2.5 text-center dark:bg-blue-600 dark:hover:bg-blue-700 dark:focus:ring-blue-800">User profile</button><div id="popover-user-profile" role="tooltip" class="inline-block absolute invisible z-10 w-64 text-sm font-light text-gray-500 bg-white rounded-lg border border-gray-200 shadow-sm opacity-0 transition-opacity duration-300 dark:text-gray-400 dark:bg-gray-800 dark:border-gray-600">    <div class="p-3">        <div class="flex justify-between items-center mb-2">            <a href="#">                <img class="w-10 h-10 rounded-full" src="/docs/images/people/profile-picture-1.jpg" alt="Jese Leos">            </a>            <div>                <button type="button" class="text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:ring-blue-300 font-medium rounded-lg text-xs px-3 py-1.5 dark:bg-blue-600 dark:hover:bg-blue-700 focus:outline-none dark:focus:ring-blue-800">Follow</button>            </div>        </div>        <p class="text-base font-semibold leading-none text-gray-900 dark:text-white">            <a href="#">Jese Leos</a>        </p>        <p class="mb-3 text-sm font-normal">            <a href="#" class="hover:underline">@jeseleos</a>        </p>        <p class="mb-4 text-sm font-light">Open-source contributor. Building <a href="#" class="text-blue-600 dark:text-blue-500 hover:underline">flowbite.com</a>.</p>        <ul class="flex text-sm font-light">            <li class="mr-2">                <a href="#" class="hover:underline">                    <span class="font-semibold text-gray-900 dark:text-white">799</span>                    <spa>Following</span>                </a>            </li>            <li>                <a href="#" class="hover:underline">                    <span class="font-semibold text-gray-900 dark:text-white">3,758</span>                    <span>Followers</span>                </a>            </li>        </ul>    </div>    <div data-popper-arrow></div></div>

Here's an example where you can show a description and image similar to the Wikipedia popovers:

Source code:

Placement

You can also set the position of the popover component relative to the trigger element by using the data-popover-placement="{top|right|bottom"left}" data attribute and its values.
