Hi @DenaHome 

To complete your requests, please follow these steps:

1. Go to Shopify Admin > Online Store > Theme > Customize > Theme Settings > Custom CSS https://prnt.sc/i8ljAMlHJUKl
2. Paste the code provided into the Custom CSS section.

Option 1: 

div.shopify-section:has(.customer.login) {
    background-image: url("link-image");
    background-position: center;
    background-size: cover;
}

Here is the result: https://prnt.sc/m70IMMphgosc ( use this code if you want to insert the image as background) 

Option 2: 

div.shopify-section:has(.customer.login) {
    background: black !important;
}
div.shopify-section:has(.customer.login) * {
    color: white !important;
}

Here is the result: https://prnt.sc/1s7vveovMstD ( use this one if you just want to change the color) 

I hope this helps

Best,

Daisy

Actually, I'm talking about this part, I've reviewed a few sites here and I want people's login part to be like this and I want it to be like this.
