How can I create a hero section with a changing background image every 4 seconds, similar to Udemy's homepage?

To create a hero section with a changing background image every 4 seconds, similar to Udemy's homepage, you can follow these steps in Webflow:

1. Prepare your images: Gather the images you want to use for the background and make sure they are optimized for the web. Keep in mind that images with a large file size can impact the loading time of your website.

2. Create a section: Start by creating a new section for your hero area. This can be done by adding a new div or section element to your page.

3. Add a background image: Select the section and go to the style tab. Under the Background section, choose the background image option and upload the first image you want to use. Adjust the background position and size if necessary.

4. Set up interaction: With the section still selected, go to the interactions panel and click on the "+" button to add a new interaction. Choose the "While page is scrolling" trigger.

5. Add a timer: In the interactions panel, click on the "+" button in the Actions section and choose "Start Timer." Set the duration to 4 seconds and make sure the repeat option is selected.

6. Change background image: In the interactions panel, click on the "+" button in the Actions section again and choose "Set Background Image." Upload the second image you want to use. Repeat this step for each image you want to cycle through.

7. Create a loop: In the interactions panel, click on the "+" button in the Actions section once more and choose "Start Animation." Set the duration to 0 seconds and choose the "Loop" option.

8. Preview and adjust: Preview your website to see the changing background images in action. If the timing or transition between images is not to your liking, go back to the interactions panel and adjust the timing or animations as needed.

That's it! You have successfully created a hero section with a changing background image every 4 seconds, similar to Udemy's homepage. Feel free to customize the duration, images, and other settings to fit your design and branding.
