If you can add container class as wrapper on those widget it will work fine. Here is alternatives custom CSS

aside#ninja_forms_widget-3 {
    max-width: 1170px;
    margin: 0 auto;
}

.map-section {
    max-width: 1170px;
    margin: 0  auto;
}

aside#medical_circle_featured-1 {
    max-width: 1170px;
    margin: 0 auto;
}

Best Regards!
