Hi @StuKellyMotorsp,

Go to Online Store, then Theme, and select Edit Code.
Search for base.css/theme.css/style.css file Add the provided code at the end of the file.

.card-wrapper .button--secondary:after {
    --border-opacity: var(--buttons-border-opacity);
    box-shadow: 0 0 0 5px #48ef13 !important;
}

Hi @StuKellyMotorsp 

TRy this one. 

1. From your Shopify admin dashboard, click on "Online Store" and then "Themes".
2. Find the theme that you want to edit and click on "Actions" and then "Edit code".
3. In the "Assets" folder, click on "base.css, style.css or theme.css" file, depending on which file your theme uses to store its CSS styles. At the bottom of the file, add the following CSS code:

.button:not([disabled]):hover::after,
.shopify-challenge__button:hover::after,
.customer button:hover::after,
.shopify-payment-button__button--unbranded:hover::after {
    --border-offset: 1.3px;
    box-shadow: 
        0 0 0 calc(var(--buttons-border-width) + var(--border-offset)) #48ef13, 
        0 0 0 calc(var(--buttons-border-width) + 1px) #48ef13 !important;
}

.button:after, 
.shopify-challenge__button:after, 
.customer button:after, 
.shopify-payment-button__button--unbranded:after {
    box-shadow: 
        0 0 0 calc(var(--buttons-border-width) + var(--border-offset)) #48ef13, 
        0 0 0 calc(var(--buttons-border-width) + 1px) #48ef13 !important;
}
