Recently, I came across this website that I wanted to display in a webview on Android. Surprisingly, it displayed correctly but not in full screen. After some research and troubleshooting, I suspect there might be an issue with the css causing this problem. Unfortunately, I haven't been able to pinpoint the exact cause yet. Attached is a screenshot of how it appears on my phone. My ultimate goal is for the background to take up the entire screen. Do you think this is achievable?
