To make a background video fullscreen on Webflow while maintaining full screen on different resolutions, you can follow these steps:
1. Start by adding a video element to your Webflow project. You can do this by dragging and dropping the "Video" component from the elements panel onto your desired section or container.
2. Upload the video file you want to use as your background video. Make sure the video is in the desired 1920x1080 resolution.
3. Within the video settings, click on the video element and navigate to the settings panel. Under the "Video" tab, upload your video file. Webflow will automatically handle your video compression and optimization.
4. After uploading the video, go to the "Background" tab in the settings panel. Here you can set the background video settings and make it fullscreen. Select the option "Cover" from the "Size" dropdown menu. This will ensure the video fills up the entire container or section.
5. Now, you'll need to set up some custom code to override Webflow's default behavior and force the video to stretch and fill the entire screen on larger resolutions. Click on the gear icon on the top-right of the Webflow Designer, then click on "Custom Code".
6. In the Custom Code panel, go to the "Head Code" section. Add the following CSS code:
```css
.video-background {
height: 100vh; /* Set the video height to the full viewport height */
width: 100%; /* Set the video width to 100% of the container */
object-fit: cover; /* Maintain aspect ratio and fill the container */
object-position: center top; /* Position the video at the center top */
}
```
7. Click "Save Changes" and exit the Custom Code editor.
By applying this custom code, your background video will now stretch and fill the entire screen on resolutions that are larger than 1920px. It will maintain its aspect ratio and appear pixelated on larger resolutions, which is what you prefer.
To address your question on the difficulty of achieving this, the challenge lies in ensuring that the video fills the screen while maintaining its aspect ratio across different resolutions. Webflow's native settings only provide basic functionality, but with the addition of custom code, you have greater control over the styling and behavior of your elements.
Keep in mind that with this approach, there will be some degree of cropping or letterboxing on screens with resolutions smaller than 1920x1080, as the video will always attempt to fill the entire container. If you need to accommodate smaller resolutions more specifically, you may need to explore alternative techniques or use media queries to adjust the video size accordingly.
