To complete your requests, please follow these steps:
- Go to Shopify Admin > Online Store > Theme > Customize > Theme Settings > Custom CSS https://prnt.sc/i8ljAMlHJUKl
- Paste the code provided into the Custom CSS section.
.section-header .header-wrapper * {
fill: white !important;
color: white !important;
}
html .section-header.scrolled-past-header .header-wrapper * {
fill: black !important;
color: black !important;
}
Here is the result: https://prnt.sc/Tvrs1GcXeGpw
This will change everything you requested to black, except the logo, as it is image (png) so it can’t be changed using the code, but you need to use an image changing tool like Photoshop, Canva, and re-upload it
I hope this helps
Best,
Daisy
