# Theme Builder

The theme system in Wisej.NET is quite powerful and goes beyond simple CSS, LESS or SASS. It is entirely contained in a single JSON file, including colors, images, fonts and appearances. You can virtually change any visual aspect of Wisej controls through a single theme file.

## Main Window

## Installation

The Theme Builder application doesn't need to be installed. It's a single self-contained executable that you can freely distribute to other developers or graphic designer professionals.
