Current UX Trends

With many Mobile Web Apps using modern javascript frameworks, what are the challenges for improving UI Design without CSS? Is this a step backwards for User Experience testing and UI prototyping?

Worldwide

The popularity of ReactJs has surpassed the Angular framework worldwide, while there has been a steady decline in JQuery manipulation of the UI. There also appears to be a gradual decline in CSS, which may indicate a shift to a javascript based style implementation used by React.

North America

Silicon Valley and media centers like Vancouver BC and Los Angeles are all seeing adoption of ReactJS over Angular, which leaves questions about the future of CSS in mobile app development.

On the West Coast, React has become the preferred javascript framework for mobile web apps. Even in the Puget Sound region where Angular has significantly more developer positions, that trend has been declining in favor of React.
