How can I implement a full page lottie animation with Webflow that maintains its aspect ratio regardless of the viewport size? I have already tried using "object-fit: cover" but it didn't solve the issue. I found that I need to use the parameter "rendererSettings:{ preserveAspectRatio:'none' }" in Bodymovin, but I'm not sure how to implement it while still using the Webflow interface for lottie animation. Any suggestions?

To implement a full-page Lottie animation in Webflow while maintaining its aspect ratio, you can follow these steps:

1. Prepare your Lottie animation: Make sure you have your Lottie animation file ready. You can export it using Adobe After Effects or any other animation software that supports the Lottie format.

2. Upload your Lottie file: In the Webflow Designer, go to the Assets panel and upload your Lottie animation file. Once uploaded, wait for it to process.

3. Add a div block: Drag and drop a div block onto your page where you want the Lottie animation to be displayed. You can adjust the size and position of the div block as needed.

4. Insert the Lottie animation element: Select the div block and click on the "Add Elements" button in the toolbar. Search for "Lottie" and choose the Lottie Animation element. This will add the Lottie Animation component to your page.

5. Link the Lottie animation: In the Lottie Animation element's settings panel on the right, click on the "Choose animation" button. Select the Lottie file you uploaded in step 2.

6. Configure the Lottie settings: In the Lottie Animation element's settings panel, you can customize various parameters. To maintain the aspect ratio of the animation regardless of viewport size, you can add custom code to the tag. Unfortunately, the Webflow interface for Lottie Animation doesn't provide an interface for specifying the "rendererSettings:{ preserveAspectRatio:'none' }" parameter directly.

7. Add custom code: To implement the "rendererSettings:{ preserveAspectRatio:'none' }" parameter, you can add custom code to the section of your page. To do this, go to the page settings by clicking on the gear icon in the left sidebar. In the "Custom Code" tab, paste the following code snippet:

```

```

Make sure to replace `.lottie-animation` with the class or ID of your Lottie Animation element's container (the div block from step 3), and `.lottie-animation-element` with the class or ID of the Lottie Animation element itself.

8. Publish and test: Save your changes, publish your site, and test the Lottie animation on different viewport sizes. The animation should now maintain its aspect ratio regardless of the screen size.

By following these steps and incorporating the custom code snippet, you can implement a full-page Lottie animation in Webflow while ensuring it maintains its aspect ratio across different viewport sizes.
