Lately I used custom fonts in my website using CSS’s @font-face method. The custom fonts render OK on Android’s Chrome browser but not the Stock browser nor Webview Control. It turns out that my CSS includes this code, which prevents the Webview Control to render custom fonts:
Just delete that line of CSS code gets custom fonts rendering OK on Webview.
BTW, Webview seems to works with .ttf, not .woff font files.
