When viewed on an iPhone, I am told that this sets the width of the display unlike the view on my Android phone where the ad is cropped and the content of the web page takes up the full width ot the screen. This is true in either Portrait or Landscape mode.
The following article suggests that the problem is created because the Safari browser on the iPhone assumes a viewport of 980 px and scales to that.
The solution suggested is to put the following code in the header:
<meta name="viewport" content="initial-scale=1" />I have now done this.
Would anyone with an iPhone please check the website and see whether the page content is displayed using the full width of the screen and the banner ad is now cropped.
Any other thoughts on this would be most welcome.
