Custom code for logo image SS 7.1

Site URL: https://harvestercapital.com

Hello, I tried searching for information about this, but was only able to find questions related to different versions of SS (I'm on 7.1), which I tried just to check, and was unsuccessful.

In my page, I have a dark and a light view depending on page. I have a dark and light logo image, and would like to substitute the primary logo file for the alternate for the pages with light background. (I chose dark for the home page). 

I would imagine there is a relatively simple code injection that can be added to each page referencing the alternate file I uploaded under Design>Custom CSS>Manage Custom Files. 

Any help is appreciated.

To change logo on One Page, add to Page Settings > Advanced > Header

<style>
  .header-title-logo img {
    visibility: hidden;
}
.header-title-logo a {
    background-image: url(https://beaverhero.com/wp-content/uploads/2019/07/coffee-beans-1082116_640-min.jpg);
    background-size: cover;
    background-repeat: no-repeat;
    background-position: center center;
}
</style>

Thank you, that worked like a charm.
