Hi there,
Welcome to SeaTheme forum.
It is possible by custom CSS(“Appearance > Customize: Additional CSS”):
label[for="wp-comment-cookies-consent"] {
font-size: 14px;
}
@media (min-width: 768px) and (max-width: 991.98px){
.responsive-ux label[for="wp-comment-cookies-consent"] {
font-size: 14px;
}
}
@media (max-width: 767px){
.responsive-ux label[for="wp-comment-cookies-consent"] {
font-size: 12px;
}
}
Regards!
