Wix site in C# webview problem, two white borders

Hello everyone, I hope you’re doing well. Can anyone suggest alternative ways to achieve the same functionality as “WebSettings settings = webView.getSettings(); settings.setUseWideViewPort(true);” of Java when working with a WebView control, specifically to address the issue of having two white borders on the sides of the control? I’m particularly interested in solutions using C# . Thank you in advance!
