Shopping cart button background and font change

hi y'all

I want the background colour of the 'Checkout button' to be #4b0719 (maroon), and the font to be Adele (which is the sitewide font I use).

Thanks in advance

It looks like you solved with this CSS?

.checkout-button span {
    font-family: 'adelle-web' !important;
}
.checkout-button {
    background: #4b0719 !important;
}
