Overview

Metronic supports dynamic theme mode switching to both Dark and Light modes and storing the user's preference in browser's local storage.

Quick Setup

Change the theme mode by setting data-theme="dark"or data-theme="light"attributes to the page's root <html> tag. Works for background colors, images, text colors, border colors, shadows and even gradients.

<html data-theme="dark">
....
</html>

The theme mode can be set invidivually for particular page blocks despite having different mode for the page:

Instagram Social Media

87%

<!-- Dark mode -->
<div data-theme="dark">
....
</div>

<!-- Light mode -->
<div data-theme="light">
....
</div>

The theme mode can be switched through unified Theme Mode Switcher opened by the sun or moon icons click in the page's header block. The theme mode switch feature is handled by StudioThemeModejavascript class and allows saving user's preference in the browser's local storage.

Flip Elements

Use .theme-light-showand .theme-dark-showutility classes to flip an element for particular theme mode:

<!-- Show for light mode only-->
<div class="theme-light-show">
....
</div>

<!-- Show for dark mode only-->
<div class="theme-dark-show">
....
</div>

Flip Images

Use .theme-light-showand .theme-dark-showutility classes to flip image for required mode:

<!-- Show for light mode only -->
<img alt="Logo" src="/V2/dist/assets/logos/default.svg" class="theme-light-show h-35px"/>

<!-- Show for dark mode light-->
<img alt="Logo" src="/V2/dist/assets/logos/default-dark.svg" class="theme-dark-show h-35px"/>

Use a custom class defined inside <style>tag for background image flip support:

<!--begin::Image placeholder-->
<style>
 .image-placeholder {
  background-image: url('assets/example.svg');
 }

 [data-theme="dark"] .image-placeholder {
  background-image: url('assets/example-dark.svg');
 }
</style>
<!--end::Image placeholder-->

<!-- Dark and light background image support -->
<div class="image-placeholder">
...
</div>
