Change specific button color without affecting entire theme

[Revail]

How do I only make this button a full black and white button instead of outlined?
I recently changed my add-to-cart button to transparent with a black outline but it seemed to have change all my store's buttons to that

Is there a way where I can change only my home page's 'SHOP THE COLLECTION' to a full black and white button? Thanks!

Hii, @Revail 
Paste this code on top of the theme.scss file.

a.btn.btn--primary.hero__btn {
    background-color: black !important;
    color: white !important;
}

Thank You.
