Solution 1 :

You could use CSS variables and a little bit of JavaScript to switch themes.

Define the theming in the .light or the .dark then set the class of the body to it. It will set the variables to the theme color.

Ex:

function toLight() {
  document.body.classList.remove('dark');
  document.body.classList.add('light');
}

function toDark() {
  document.body.classList.remove('light');
  document.body.classList.add('dark');
}
.light {
  --font-color: #111;
  --bg-color: #fff;
}

.dark {
  --font-color: #eee;
  --bg-color: #111;
}

p, h1 {
  color: var(--font-color);
}

body {
  background-color: var(--bg-color);
}
<body class="light">
  <h1>title</h1>
  <p>text blah blah</p>
  
  <button onclick="toDark()">switch to dark</button>
  <button onclick="toLight()">switch to light</button>
</body>

Problem :

Plz include the respective HTML/CSS/JS.

You probably need to create a button that once the user clicks on it, it will add a class to the and from there you change your CSS styles or CSS source.

so i could litteraly copy and paste that?

you’ll need to add some CSS to style the elements for light and dark mode (with variables) and add some logic for the toggle button. But for the rest, I think it’ll work.
