I need to change the design of the newsletter block in the footer. I tried to find a code to customize it but I cant. I want it to look like our "contact us" form for coherence but it looks very different. 

we a smaller size for the whole form and transparent fields. Is that possible?

Add the below code in Custom CSS 

#footer-sections .sqs-block-newsletter {
    background : transparent;
}

#footer-sections .sqs-block-newsletter input {
    background : transparent;
    border : solid var(--form-field-border-thickness) var(--dynamic-border-color, #A9A9A9);
    border-radius: .4rem;
}

#footer-sections .sqs-block-newsletter input::placeholder {
    color : #fff;
}

#footer-sections .sqs-block-newsletter button {
    background : #fff!important;
    color : #000!important;
}
