dark/light mode

Arash.Ranjbar · 29. November 2021

hi

I use these codes for make a dark-light mode:

js:

const toggleSwitch = document.querySelector('.daa input[type="checkbox"]');
const currentTheme = localStorage.getItem('theme');

if (currentTheme) {
    document.documentElement.setAttribute('dark-mode', currentTheme);
  
    if (currentTheme === 'night') {
        toggleSwitch.checked = true;
    }
}
function switchTheme(e) {
    if (e.target.checked) {
        document.documentElement.setAttribute('dark-mode', 'night');
        localStorage.setItem('theme', 'night');
    }
    else {        document.documentElement.setAttribute('dark-mode', 'light');
          localStorage.setItem('theme', 'light');
    }    
}
toggleSwitch.addEventListener('change', switchTheme, false);

html:

        <label class="daa showguest" for="checkbox">
	<input class="l" type="checkbox"></label>
        <script>

css:

.1 {
	font-size: 1em;
	line-height: 1.5;
	display: block;
	margin-bottom: 1.5em;
}
html[dir="rtl"] .daa {
	padding: 1.5em 0 0 0;
	text-align: center;	
    direction:ltr;
    position:relative;
    margin-left:-21px;
    top:-5px;
}
html[dir="ltr"] .daa {
	padding: 1.5em 0 0 0;
	text-align: center;	
    direction:ltr;
    position:relative;
    margin-right:-21px;
    top:-5px;
}
html[dir="ltr"] .showguest {
  margin-right: 1px;
}
html[dir="rtl"] .showguest {
  margin-left: -7px;
}
.l {
	background-color: rgba(0, 0, 0, 0.11);
	border-radius: 0.75em;
	box-shadow: 0.125em 0.125em 0 0.125em rgba(0,0,0,0.3) inset;
	color: #f5f8f9;
	display: inline-flex;
	align-items: center;
	margin: auto;
	padding: 0.15em;
	width: 3em;
	height: 1.5em;
	transition: background-color 0.1s 0.3s ease-out, box-shadow 0.1s 0.3s ease-out;
	-webkit-appearance: none;
	-moz-appearance: none;
	appearance: none;
}
.l:before, .l:after {
	content: "";
	display: block;
		box-sizing: border-box;
	margin: 0;
	padding: 0;
}
.l:before {
	background-color: #fdea7b;
	border-radius: 50%;
	width: 1.2em;
	height: 1.2em;
	transition: background-color 0.1s 0.3s ease-out, transform 0.3s ease-out;
	z-index: 1;
}
.l:after {
	background:
		linear-gradient(transparent 50%, rgba(0,0,0,0.15) 0) 0 50% / 50% 100%,
		repeating-linear-gradient(90deg,#bbb 0,#bbb,#bbb 20%,#999 20%,#999 40%) 0 50% / 50% 100%,
		radial-gradient(circle at 50% 50%,#888 25%, transparent 26%);
	background-repeat: no-repeat;
	border: 0.25em solid transparent;
	border-left: 0.4em solid #d8d8d8;
	border-right: 0 solid transparent;
	transition: border-left-color 0.1s 0.3s ease-out, transform 0.3s ease-out;
	transform: translateX(-22.5%);
	transform-origin: 25% 50%;
	width: 1.2em;
	height: 1em;
}
/* Checked */
.l:checked {
   background-color: rgb(100, 101, 104);
   box-shadow: 0.125em 0.125em 0 0.125em rgb(100, 101, 104) inset;
}
.l:checked:before {
	background-color: currentColor;
	transform: translateX(125%)
}
.l:checked:after {
	border-left-color: currentColor;
	transform: translateX(-2.5%) rotateY(180deg);
}
/* Other States */
.l:focus {
	/* Usually an anti-A11Y practice but set to remove an annoyance just for this demo */
	outline: 0;
}

in css I use this structure:

/*for dark*/
html[dark-mode="night"] body {
background: red;
}
/*for light*/
body {
background: #fff;
}

when I put HTML code in userbar template everything good works but when I wanna put this code in mobilenavbar or mobilenavigation it doesn't work and in search console I got below error:

Uncaught SyntaxError: redeclaration of const toggleSwitch
