iOS Question B4i v6.50 webview text size problem

[kisoft]

HI
Internal WebView is now based on WKWebView. There is also a new EvaluateJavaScript method.
There was a problem displaying text in the web view (HTML file). The text is much smaller than in the old web view. What should be done to ensure that the text is displayed correctly. I don't want to change the properties of HTML files, there are over 1000 of them.

Try to add <meta name="viewport" content="initial-scale=1.0" /> in header.

I load the text from an html file

WKWebView1.LoadHtml(File.ReadString(File.DirAssets,myfile.html))

Do I need to add this to every html file? Can I add it using code? ... but how do I do it?

For example, if you use low case in HTML:

Dim s As String = File.ReadString(File.DirAssets,myfile.html)
s = s.Replace ("<head>", $"<head>
<meta name="viewport" content="initial-scale=1.0" />"$)
WKWebView1.LoadHtml (s)
