 ### **Styling**
 
-AXSharp.Presentation.Blazor contains in-built styles. Styling is provided by [Bootstrap library](https://getbootstrap.com/). In-built styles can be customized with Sass technology, which will produce SCSS files. SCSS files can be compiled into one CSS file which can be used as application-wide style.
+AXSharp.Presentation.Blazor contains in-built styles. The styling is provided by `momentum.css`, a custom CSS file built with [Tailwind CSS](https://tailwindcss.com/). This approach consolidates all styling into a single dependency for better maintainability.
 
-Currently, the framework contains a default style that can be added as a reference in the Blazor application file *_Host.cshtml* in the following way:
+To add the styles to your Blazor application, reference the CSS file in your *_Host.cshtml* (or *App.razor* for .NET 8+ Blazor applications):
 
+```html
+<link rel="stylesheet" href="/_content/AXSharp.Presentation.Blazor.Controls/css/momentum.css">
 ```
- <link rel="stylesheet" href="/_content/AXSharp.Presentation.Blazor.Controls/css/ix-bootstrap.min.css">
+
+If you are also using the Operon library, include its stylesheet as well:
+
+```html
+<link rel="stylesheet" href="/_content/Inxton.Operon/css/momentum.css">
 ```
-It is possible to add built-in javascript libraries as well:
+
+#### Building Custom Styles
+
+If you need to customize the styles, you can modify the Tailwind CSS source file and rebuild the `momentum.css`. The source file is located at:
+
 ```
-    <script src="/_content/AXSharp.Presentation.Blazor.Controls/js/ix-bootstrap.bundle.min.js"></script>
-    <script src="/_content/AXSharp.Presentation.Blazor.Controls/js/jquery-3.6.0.min.js"></script>
+src/AXSharp.blazor/src/AXSharp.Presentation.Blazor.Controls/wwwroot/css/tailwind.css
 ```
+
+To rebuild the styles:
+
+1. Ensure Node.js is installed on your system
+2. Navigate to the `AXSharp.Presentation.Blazor.Controls` directory
+3. Run `npm install` to install dependencies (if not already done)
+4. Run the Tailwind CLI to build the CSS:
+   ```
+   npx @tailwindcss/cli -i ./wwwroot/css/tailwind.css -o ./wwwroot/css/momentum.css --minify
+   ```
+
+> **Note:** The build process automatically handles the Tailwind CSS compilation when you run the project build script.
