LitPopup

A customizable lightweight popup plugin with no dependencies.

Why?

I needed full control over popup animation and its lifecycle.

Installation

NPM

Install it from NPM: npm i lit-popup

Usage

Include css from node_modules/lit-popup/dist/css/lit-popup.min.css (or write your own)

<div class="lit-popup" data-lit-popup="popup">
    <div class="lit-popup-container">
        <!-- Layout here -->
    </div>
</div>

import LitPopup from 'lit-popup';

const popup = new LitPopup('name');
