Discussion on: RE: Add dark mode to any website with just a few lines of code

buat_dark = () => {

    s.appendChild(document.createTextNode('html{-webkit-filter:invert(100%) hue-rotate(180deg) contrast(70%) !important; background: #fff;} .line-content {background-color: #fefefe;}'));
    h.appendChild(s); 
    localStorage.setItem('dark', 'true')

}

localStorage.dark == 'true' ? buat_dark() : ''

$(".dark").click(() => dark())
