How do I add the code (backgroundAlpha:1) to the hero section in Webflow for a background?

In Webflow, you can add custom code to the hero section to modify the background properties, such as the background alpha value. Here's how you can accomplish this:

1. Select the hero section: Open your Webflow project and go to the page where the hero section is located. Click on the hero section to select it.

2. Access the Settings panel: On the right side of the Webflow Designer, you'll find the Settings panel. Click on the "Settings" icon (represented by a gear icon) to open it.

3. Add a custom attribute: In the Settings panel, scroll down to the "Custom Attributes" section. Click on the "+ Add Attribute" button to create a new custom attribute.

4. Define the custom attribute: In the input field that appears, enter "style". This attribute will allow you to add custom CSS to the hero section.

5. Add the CSS code: Once you've defined the custom attribute, you can now add the CSS code to modify the background alpha value. Type in the following code inside the value field:
`background-color: rgba(0, 0, 0, 0.5);`
This code sets the background color to black (RGB: 0, 0, 0) with an alpha value of 0.5. You can adjust the color and alpha value to fit your design needs.

6. Save the changes: After adding the CSS code, click outside the input field or press Enter to save the changes.

7. Preview and publish: Now, you can preview the hero section with the updated background alpha value by clicking on the "Preview" button in the top-right corner of the Webflow Designer. If you're satisfied with the changes, publish your project to make the modifications live on your website.

By following these steps, you'll be able to add the code `background-color: rgba(0, 0, 0, 0.5);` or any other CSS code you desire, to modify the background alpha value of the hero section in Webflow. Remember to adjust the color values and alpha value to achieve your desired background effect.
