Created attachment 459778 [details] How it looks like on iPad `configuration.defaultWebpagePreferences.preferredContentMode` has been set to `.mobile` But “webkit-text-size-adjust” doesn't work correctly on iPad. On iPhone, set “webkit-text-size-adjust” with 200%, both font-size and line-height will be scaled. But on iPad, only font-size gets scaled, line-height doesn't change. * STEPS TO REPRODUCE 1. Create a WKWebView with `config.defaultWebpagePreferences.preferredContentMode = .mobile` 2. loadHTMLString in WebView with "<h1 style="-webkit-text-size-adjust: 200%; font-size: 100px; line-height: 100px">Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!Hello, World!</h1>" 3. Run the app on iPhone and iPad * RESULTS Correct: On iPhone, the font-size and the line-height are all scaled to 200px Incorrect: On iPad, the font-size is scaled but the line-height is still 100px
