When you're experiencing issues with the `100vh` rule on the nav container in Webflow, specifically on mobile devices where there is some scrollable space, there could be several potential causes for this behavior. Let's explore a few possible reasons and solutions:
1. Mobile browser UI: On some mobile browsers, there may be a UI that sits on top of the webpage, reducing the available viewport height. This can result in unexpected scrollable space below the `100vh` element. To overcome this, you can try using the `100%` height value instead of `100vh` for the affected container, as it calculates the height relative to the parent element, which may exclude the browser UI.
2. Oversized content: If the nav container or any of its child elements have content that exceeds the height of the viewport, it can cause the container to stretch beyond `100vh` and result in scrollable space. Check if there are elements with excessive padding, margins, or large font sizes, as these can contribute to the overall height of the container. Adjusting these settings might help maintain the `100vh` height without any extra scrolling.
3. Layout structure: The issue may arise if the nav container is nested within another element that has a specified height or is influenced by other properties like flexbox or grid. Review the layout structure and make sure all parent containers are appropriately configured without any conflicting settings that could affect the height calculations.
4. CSS overrides: Any custom CSS or conflicting stylesheets you have added to the project might interfere with the `100vh` calculation. Inspect the affected container in the browser's developer tools and see if there are any overridden styles that are affecting the height. Adjust or remove these overrides to restore the desired behavior.
5. Webflow bugs: While Webflow is a powerful platform, occasionally, there might be bugs or inconsistencies. It's worth checking the Webflow community forum or reaching out to their support team to investigate if others have experienced similar issues and if there are any known workarounds or updates available.
Remember to test your changes on multiple mobile devices and browsers to ensure consistent behavior across various platforms. If you are still unable to resolve the issue, providing more specific details about your project and sharing a read-only link could help the Webflow community or support team offer tailored assistance.
