UIWebView background is set to Clear Color, but it is not transparent
Also set :
[webView setBackgroundColor:[UIColor clearColor]];[webView setOpaque:NO];
/*for ios please set this*/ [webViewFirst setOpaque:NO]; /*for html please set this*/ <body style="background:none">
Besides setting your webview's background to clear color, also make sure that you set opaque to false.
