How can I make a hero video in Webflow automatically adjust size and maintain the 16:9 aspect ratio on tablet and mobile devices?

To make a hero video in Webflow automatically adjust size and maintain the 16:9 aspect ratio on tablet and mobile devices, you can follow these steps:

1. Prepare your video: Before uploading your video, make sure it is already formatted with a 16:9 aspect ratio. This means that the width should be 16 units for every 9 units of height. You can use video editing software like Adobe Premiere Pro or online tools to resize and export your video with the desired aspect ratio.

2. Create a section: In the Webflow Designer, add a new section to your page where you want the hero video to be displayed. You can use a predefined section or create a new one.

3. Add a video element: Inside the section, add a video element by dragging and dropping it from the Webflow Elements panel. By default, the video element will have a fixed width of 100%. Make sure the video element is selected.

4. Set the aspect ratio: In the video element's settings panel on the right-hand side, set the aspect ratio to 16:9. This setting ensures that the video element maintains the desired aspect ratio, regardless of the device size.

5. Adjust positioning and size: Select the section and go to the section's settings panel. Set the position of the section to relative and the width to 100%. This allows the section to expand or contract based on the device's screen size.

6. Styling and responsive adjustments: Customize the section and video element's styles according to your design preferences. You may want to set a minimum or maximum height for the section, add padding or margin to create spacing, etc. Additionally, you can use Webflow's responsive design features to make further adjustments for tablet and mobile devices. For example, you can hide, resize, or reposition the video element to best fit smaller screens.

7. Test and preview: Preview your design by using the Webflow Designer's built-in preview mode or publish your site to a staging domain to see how the hero video appears and adjusts on different devices.

By following these steps, your hero video in Webflow should automatically adjust its size and maintain a 16:9 aspect ratio on tablet and mobile devices, providing a consistent and visually appealing experience across various screen sizes.
