🔧 Next.js Theming: CSS Variables for Adaptive Data Visualization

Theming is not just a choice but an important feature in modern web and mobile applications, as it allows for a more personalized, seamless, and tailored user experience. Theming becomes a must-have feature for SaaS applications integrating into other applications. Traditional theming techniques often involve hardcoded styles and rigid code configurations. This creates issues in the maintenance and scaling of applications. 

Furthermore, complexity grows even more when an application supports multiple themes across web and mobile devices. Modern CSS frameworks come with built-in theming support, but often, the themes they provide are fixed and don’t fit the needs of enterprise applications.
