I created this JS library as an open-source project to provide beautiful alert box messages, overlay box and toaster made with HTML, CSS and JS only. Feel free to contribute with a pull request or suggestions.
npm install vanillajs-components//css
import '~vanillajs-components/dist/vanillajs-components.min.css'
// javascript
import { overlay,confirm,toast,tabs,steps } from 'vanillajs-components';<head>
