Responsive Web Apps 101: What They Are and How to Build Them

A responsive web app is an interactive piece of online software that automatically adjusts its layout to fit any screen size, whether it's a desktop, laptop, tablet, or mobile device. This design approach ensures that the website looks great and functions well on all devices. Responsive design became popular as more people started using mobile devices with varying screen sizes. In comparison to native mobile apps, responsive web apps are generally easier and less costly to develop, but may not provide the same level of user experience or functionality. However, they offer greater reach and scalability due to their compatibility across all devices. Bubble is a no-code tool that makes it easy to create responsive web apps using core components like responsive columns, rows, parent-child alignment, and margins/padding.
