To dynamically change the background of every other item in a collection list in Webflow, you can use a combination of custom code and the CMS (Content Management System) features in Webflow. Here's a step-by-step guide on how to achieve this:
Step 1: Set up your Collection List
First, create a Collection List in your Webflow project and link it to the desired collection. Add a div block or any other container element inside the Collection List to represent each item in the collection.
Step 2: Apply a class to each item
Give each div block or container element inside the Collection List a unique class name. You can use the Webflow designer to apply the class to all the items or use custom code to apply it to each item separately.
Step 3: Add custom code
Click on the Project Settings in the Designer, then go to the Custom Code tab. In the '<head>' section, add a `<style>` block with the following code:
```css
<script>
.your-item-class:nth-child(even) {
background-color: #your-color-code;
}
</script>
```
Replace `.your-item-class` with the class name you assigned to each item in the previous step, and replace `#your-color-code` with the desired background color code.
Step 4: Publish and test
Publish your site and navigate to the page where the collection list is displayed. You should now see that the background color of every other item in the collection list has changed according to the custom code you added.
By following these steps, you can dynamically change the background of every other item in a collection list in Webflow. This method allows you to create visually appealing designs and helps to differentiate items within a list.
