What's the Wisej.NET Theme Builder
Edit any aspect of a Wisej.NET theme – it’s a single, self-contained, readable JSON file. You can use the intuitive tree view or the code editor view to navigate to any component. There is no limit to the complexity of a Wisej.NET theme, and no limit to the themeable properties. Unlike plain CSS, Wisej.NET can theme anything, including custom properties and custom states.
