Web Push for Web Apps on iOS and iPadOS. iOS and iPadOS 16.4 beta 1 finally brings web push notifications to iOS. User’s need to add an app to their home screen and then approve notification access to get this functionality, which also includes the ability for apps to update a badge on their icon. Thankfully you don’t need paid membership of the Apple Developer Program ($99/year) in order to send notifications. # 17th February 2023, 12:28 am

Supporting logical properties. A frustrating reminder from Jeremy Keith that Safari is not an evergreen browser: older iOS devices (1st gen iPad Air for example) get stuck on the last iOS version that supports them, which also sticks them with an old version of Safari, which means they will never get support for newer CSS properties such as inline-start and block-end. Jeremy shows how to use the @supports rule to hide this new syntax from those older browsers. # 1st October 2022, 1:03 am

Visualizing WebKit’s hardware acceleration. Command line flags for launching Safari (and the iOS simulator) in a way that highlights areas of the screen that are being hardware accelerated—particularly useful if you are using the “-webkit-transform: translate3d(0,0,0)” trick. # 27th June 2011, 10:31 am
