How can font color be changed based on background color zones in Webflow? What script can easily achieve this, such as black font for the upper left zone, white font for the lower zone, and white font for the upper right zone?

To change font color based on background color zones in Webflow, you can achieve this using custom code and applying different classes based on the position of the element or the background zone. Here's an example of how you can achieve this using CSS and JavaScript:

1. First, you'll need to create a class for each background zone. Let's say you have three zones: upper left, lower, and upper right. You can create classes with these names in Webflow's class manager.

2. Next, you'll need to add custom CSS code to target each background zone and apply the desired font color. For example, you can add the following code to your project's Custom Code section or in an external CSS file:

```css
.upper-left {
color: black;
}

.lower {
color: white;
}

.upper-right {
color: white;
}
```

3. Now, you'll need to add JavaScript code to apply the correct class based on the position of the element. You can achieve this by adding an HTML embed element to your project and placing the following JavaScript code inside it:

```javascript

```

Make sure to replace `.your-element-selector` with the appropriate selector for the element you want to change font color.

4. Lastly, you'll need to make sure to place the HTML embed element before the element you want to change font color and adjust the CSS and JavaScript code to fit your specific layout and scenario.

By following these steps, you can dynamically change the font color of an element based on its background zone using Custom CSS and JavaScript in Webflow.
