Different image for dark mode

[ayaspan]

Hi all,

I realize this theme has been addressed before but not specifically this issue. I'm trying to create a Marketo template with modules that come with a preset image. There is a regular version of the image, and then there's an altered version that would ideally replace it if the user is in dark mode. What can I put in the HTML/CSS of this module/template to make that happen? Keep in mind I have limited expertise, I have had to do a few projects in coding throughout my career but it's a lot of trial-and-error and searching as I go, so I'm not super caught up on the lingo. Appreciate any help, thank you!

Cheers,

Alan

Hi @ayaspan,

You have to use some CSS in the head section, for example - 

<style type="text/css">
         :root {
         color-scheme: light dark;
         supported-color-schemes: light dark;
         }
      </style>
	  
      <style type="text/css">
         @media (prefers-color-scheme: dark) {
         /* Shows Dark Mode-Only Content, Like Images */
         .dark-img {
         display: block !important;
         width: auto !important;
         overflow: visible !important;
         float: none !important;
         max-height: inherit !important;
         max-width: inherit !important;
         line-height: auto !important;
         margin-top: 0px !important;
         visibility: inherit !important;
         }
         /* Hides Light Mode-Only Content, Like Images */
         .light-img {
         display: none;
         display: none !important;
         }
      </style>

And, for image replacement in dark mode, use the below code - 

<td class="light-img">
<div class="mktoImg" id="Header-Logo" mktoname="Header Logo">
	<a target="_blank" href="" style="text-decoration:none;outline:0;">
	  <img src="" />
	</a>
</div>
</td>
<td class="dark-img" style="display:none; overflow:hidden; float:left; width:0px; max-height:0px; max-width:0px; line-height:0px; visibility:hidden;">
<div class="mktoImg" id="Header-Logo-dark" mktoname="Header Logo Dark Mode">
	<a target="_blank" href="" style="text-decoration:none;outline:0;">
	  <img src="" width="118" />
	</a>
</div>
</td>

Thanks!

Thank you so much for your answer. I am trying it now. Sorry for my delayed response; been staying up until the wee hours dealing with this template (like 2 days straight just trying to get it to look right in Outlook), just now finding the opportunity to try this out. Excited!

Just asking, sorry if this seems obvious or if I'm being nit-picky, but is the width="118" part in the dark image code necessary? If I'd like the image to display at full width, do I need to specify width? And I'm guessing "margin-top: 0" in the CSS is to make sure there's no space left by the hidden light mode image?

You can define any width there according to your needs.
