To make your Vimeo video cover the full div in Webflow, you can follow these steps:
1. Place a div block onto your Webflow canvas where you want the video to be displayed.
2. Inside the div block, insert an Embed element by clicking the "+" button or by dragging and dropping the Embed element from the Add panel on the left.
3. Copy the Vimeo video's embed code. You can get it by clicking on the "Share" button on your Vimeo video and selecting the "Embed" option.
4. Paste the Vimeo video's embed code into the Embed element in Webflow.
5. With the Embed element selected, go to the settings panel on the right-hand side. In the "Styles" section, set the width and height to be 100%. This will ensure that the video takes up the full width and height of the div block.
6. By default, the Vimeo video may have some padding or margins applied to it. To remove any unwanted spacing, you can add custom CSS code. Select the div block that contains the video and click on the "Settings" tab in the right-hand panel. Scroll down to the "Custom Code" section and click on "Add Head Code". In the code editor, add the following CSS code:
```css
```
This CSS code will position the video absolutely, stretching it to cover the entire div block.
7. Save your changes and preview your website to see the Vimeo video covering the full div in Webflow.
Remember to replace `.w-embed.w-video` with the appropriate class or selector for your Vimeo video if it differs in your Webflow project.
With these steps, you should be able to make your Vimeo video cover the full div in Webflow.
