Apple Pay on the Web
Give customers an easy and secure way to make purchases in Safari 10 or later. Apple Pay allows customers to quickly pay without entering payment, shipping, or contact information on supported websites from their Mac, iPhone, or iPad. Because card numbers aren’t used and every transaction is confirmed with a fingerprint or passcode, Apple Pay is more secure than accepting credit and debit cards.
3D Touch Behaviors for iOS
Newer iPhone models introduced Quick Actions and Peek and Pop, giving users quickly access to several actions and interactive previews. Now you can make your own Peek and Pop events using WKWebView and 3D Touch behaviors based on how much pressure a user applies to the display.
Gesture Events for macOS
Gesture events for pinching and rotation on iOS are now available on the Mac trackpad, so you can incorporate them into websites on macOS.
Safari Push Notifications
Keep users up-to-date with news and other alerts using Apple push notifications. Once users have signed up for notifications from your website in Safari on macOS, you can send push notifications that appear just like Mac app notifications even when Safari isn’t running. Users can click the notification to launch your website in Safari.
With sticky positioning, elements can remain fixed within the Safari window even as the user scrolls.
WebKit — the open source rendering engine introduced by Apple — powers Safari on macOS and iOS. WebKit features blazing performance and extensive standards support. And because it’s open source, developers can examine WebKit code and contribute to the community.
Web Audio API
Acid 2 Compliance
Designed by the Web Standards Project, Acid tests determine whether a web browser complies with emerging Internet standards. Acid 2 tests for compatibility with new features in the HTML, CSS, and PNG standards. Pioneering the standardization effort, Safari passed Acid 2 on October 27, 2005 — two and a half years before any other popular browser.
Acid 3 Compliance
Formatted XML Files
When developers download unstyled XML files, Safari presents the information in a clear document tree format, making it easier to read.
Safari can store audio and video data for web applications that use the HTML5 application cache, allowing for offline media playback and better media performance when an Internet connection is slow.
Standards Compliant IndexedDB
The newly improved, standard compliant implementation of IndexedDB lets developers store structured data for web applications on the client side and access it quickly.
Automated Testing with WebDriver for macOS
WebDriver lets you automate testing of layout, usability, navigation, and more, so you can programmatically verify the behavior of your websites in Safari.
Content Security Policy 2.0
Content Security Policy 2.0 brings you more control over the security of assets on your webpage through security policies. You can specify the sources you trust to run remote content.
Fast-Tap on iOS
Users of Safari on iOS will experience incredibly fast response rates when tapping links and buttons on webpages at their initial scale. You can also choose to offer faster tapping in lieu of double-tap to zoom for elements on a zoomed-in webpage.
Force Touch APIs
Web developers can use the Force Touch APIs to add new dimensions of interactivity to their web pages on devices that support Force Touch.
Safari supports real-time push notifications from a server. Web applications that use EventSource can receive faster, more reliable communications from the website’s server.
With support for WebSocket, Safari has a speedy, two-way communication link with a web application’s server, so online activities like chatting are faster and require less bandwidth.
With support for Mathematical Markup Language (MathML), Safari allows developers to embed mathematical notation in a web page without using an image file.
Full-Screen Web Pages
SVG 1.1 Support
By taking advantage of the Scalable Vector Graphics (SVG) support in Safari, web developers can create fonts, graphic elements, and animations on the fly that look great no matter how large or small they are. For example, mapping sites often use SVG to draw driving directions based on your location and destination.
ICC Color Profile Support
Safari uses advanced color management technology to deliver web images with rich, accurate color. In fact, it was the first browser to support International Color Consortium (ICC) profiles and has done so from day one, so the photos and images you see in your browser stay true to the originals.
XML 1.0 Support
