How can I change specific box colors to white on my website?

[docsdocs]

Looking for some guidance!

I have a shopify website that is inheriting the theme color to some boxes that should be white.

The website is docsdocs.com.br

The boxes that should be white are newsletter signup (footer), special instructions to seller (cart) and i agree to terms and conditions (cart).

@docsdocs add this css to the very end of your styles.css file and check

#note{background-color: #fff;}
.checkbox+label:before{background-color: #fff;}
#footer-signup-form .input-with-button__input{background-color: #fff;}
