GST CALCULATOR

Sure, here's an example of a responsive GST Calculator tool implemented using HTML, CSS, and JavaScript. I'll use Bootstrap for styling to make it colorful and responsive. You can add this code to your HTML file and ensure you have the Bootstrap CSS and JavaScript files linked in your project. ```html

GST Calculator

Amount:

GST Rate: 5% 12% 18% 28%

```

This code creates a simple GST Calculator with a colorful and responsive design using Bootstrap. The user can enter the amount and select the GST rate, and upon clicking the "Calculate GST" button, the calculated GST amount and total amount will be displayed below the button.
