Different logo for each template?

Is it possible to insert logo to template files/setup, so that each template would have its own logo graphic? We plan to have both light and dark template so that user could choose one he likes better. That would mean logos should be different, one negative of another. Is it possible to (easily) override basic logo uploaded via settings>logo?

You can do this by using a custom _sub_header.html file in each of your template directories.

Standard code in /templates/base/_sub_header.html is below,  Replace the code in  red with your own image.

<div class="sys_main_logo">
<div class="sys_ml" style="width:__main_div_width__;">
<div class="sys_ml_wrapper">
<bx_injection:injection_logo_before />
__main_logo__
<bx_injection:injection_logo_after />
</div>
</div>

Afterwards, your code should look something ;like that shown below.  Then just upload the logo image to your templates image directory.

<div class="sys_main_logo">
<div class="sys_ml" style="width:__main_div_width__;">
<div class="sys_ml_wrapper">
<img src="templates/tmpl_SomeTemplateName/image/.logoDark.png" />
</div>
</div>

Your templates may, or may not, already have a _sub_header.html file.  If they do not, just copy the one from the templates/base directory, then make the changes.

Got it thank you! Just replace bx_injection-lines in _sub_header.html-file in each templates folder.

Thank you for the advice, I also profited. I added just a little thing:

<a href="<bx_url_root />"><img src="<bx_url_root />templates/tmpl_SomeTemplateName/images/logoDark.png" class="mainLogo" alt="logo" /></a>

One more thing: remove the line <bx_injection:injection_logo_after /> turns off the quote next to the logo. That is why I left this line.

Thank you, these will help a lot.
