Created attachment 377856 [details] iPad - iPhone differences OS: iOS/iPadOS 13/13.1 Device: iPad only This happens on iPads running i(Pad)OS 13/13.1 only. For example: <!DOCTYPE html> <html> <body> <div style="-webkit-text-size-adjust: 56.2962293624878%;"> Sample text sample text sample text </div> <div style="-webkit-text-size-adjust: 156.2962293624878%;"> Sample text sample text sample text </div> <div style="-webkit-text-size-adjust: 356.2962293624878%;"> Sample text sample text sample text </div> </body> </html> Will be rendered without any style changes on iPad and with style applied on iPhone, both running iOS 13. See attached images for example. I'm using a basic WKWebView with the HTML above loaded using loadHTMLString:baseURL: method.

Yes, verified, "webkitTextSizeAdjust" doesn't work on iOS 13.3

I am having an issue using CSS Zoom on iPad OS (bugs.webkit.org/show_bug.cgi?id=206550). I feel that our issues are possibly related. The zoom property works just fine on Iphone and Mac, iPad has been the only effected device.

Hi all, Do you know what else apart from webkitTextSizeAdjust can be used to fix this issue? Regards,

(In reply to ecaprile from comment #10) > Hi all, > > Do you know what else apart from webkitTextSizeAdjust can be used to fix > this issue? > > Regards, You can directly manipulate fontSize style property of HTML elements. It would require parsing the existing font sizes and adjusting them for the desired scaling factor. Not sure if anyone should do this if this bug is to be fixed soon...

This is still an issue in iPadOS 13.4.1 on iPad and iPad mini with Safari and in a WkWebView. Is there an estimate or any update on the status of this issue?
