For the success and credibility of your map applications, it is important to provide users with a single URL. This universal URL should take a user to your application
and provide them with an ideal layout regardless of their screen’s size. Today’s technology is awesomely aware of the prevalence of small screen sizes. Which also means new technology incorporates mobile responsive design. This is one of the reasons ESRI is
moving away from old tech and into new tech, like Experience Builder. A great benefit of this transition is that you can configure Experience Builder mobile views based on many screen sizes. Now you can give your users one beautiful URL that does it all!
