I have created a page with complex design and different background colors and I decided to add a button to let users switch between light and dark mode
I've tried different solutions with JS, but with no success. The current workaround I use is adding two media in my CSS file. Basically, if my website appearance is set to Dark, the page will also load dark-styled theme, and Light for Browser Light Appearance.
@media screen and (prefers-color-scheme: dark)
@media screen and (prefers-color-scheme: light)
Question is: How can I let users manually change between dark-light color-schemes manually with a button using vanilla Javascript? (not with the checkbox) Ps Maybe I could somehow implement this with var(--rule) in CSS but I'm still new to this stuff and I have almost zero JS knowledge
For example:
@media screen and (prefers-color-scheme: dark) {
p, h2 {
color: #e7e7e7;
}
@media screen and (prefers-color-scheme: light) {
p, h2 {
color: #333333;
}
html button (i class/button is a placeholder)
<div class="dark-mode-container">
<div id="dark-mode-btn">
<button class="theme-switch">test</button>
<i class="fa-solid fa-moon" title="Switch to Dark mode"></i>
</div>
Here is my button inside sticky nav which I plan to use to switch modes
I'd say use javascript, create a button and a javascript function onclick.
document.body.classList.toggle("dark-mode");
This function toggles the class dark-mode on the body, so for the darkmode style add body.dark-mode infront of all CSS selectors.
const btn = document.getElementById('btn'); btn.addEventListener('click', function () { var elmWitchChange = document.getElementsByClassName('light') for (var i = 0; i < elmWitchChange.length; i++) { elmWitchChange[i].classList.toggle('dark') } })
.dark { background-color: black; color: white; }

Eligendi, recusandae?</span> <br> <div> this div does not have a light class therefore it won't be effected </div> <br> <button class="light" id="btn">toggle</button>
