How can I handle the onClick function of a button in Webflow to fill the background color of a newly created div block using JS code?

To handle the onClick function of a button in Webflow and fill the background color of a newly created div block using JavaScript code, you can follow these steps:

Step 1: Create a button in Webflow
Start by adding a button element to your Webflow project. Give it a class name or ID to reference it in your JavaScript code.

Step 2: Add a div block
Next, create a div block where you want to change the background color. You can set a default background color for the div block in Webflow's Style panel.

Step 3: Add custom code
Go to your Webflow project's custom code section. You can find it under the Project Settings > Custom Code tab. Add the following JavaScript code:

```javascript
const button = document.querySelector('.your-button-class'); // Replace '.your-button-class' with the actual class name or ID of your button
const divBlock = document.querySelector('.your-div-block-class'); // Replace '.your-div-block-class' with the actual class name or ID of your div block

button.addEventListener('click', () => {
divBlock.style.backgroundColor = 'red'; // Change the background color to the desired value
});
```

Make sure to replace `'.your-button-class'` and `'.your-div-block-class'` with the class or ID names you assigned to your button and div block, respectively.

Step 4: Publish and test
Save your changes and publish your Webflow project. The button should now trigger the onClick event, and when clicked, it will change the background color of the div block to the specified value.

You can further customize this code to include different color options or apply different styling based on user actions. Remember to adjust the syntax and class names as necessary to match your specific Webflow project.
