test.js

import themeChanger from "https://codeabinash.github.io/theme-changer.js/index.js";
let theme = new themeChanger({
    selector : '.btn',
    theme: {
        light:
            `--bg : #ddd;
            --text: #555;`,
        dark:
            `--text: #eee;
            --bg: #222;`
    }
})

Check The example from here : https://codeabinash.github.io/theme-changer.js/test/

constructor()

let theme = new themeChanger({
    selector : '.btn', // css selector (internally querySelectorAll)
    theme: {
        light: // css code 
            `--bg : #ddd;
            --text: #555;`,
        dark: // css code
            `--text: #eee;
            --bg: #222;`
    }
})

It is ok to skip the selector property, but if you skip the theme property, it will throw an error.

let theme = new themeChanger({
    theme: {
        light: 'CSS code for light theme',
        dark: 'CSS code for dark theme';
    }
})
