Types of documentation on CanIWebView
CanIWebView provides different types of documentation. The most important source is MDN Browser Compatibility Data (BCD), which allows you to check WebView support for every JavaScript API, HTML element, CSS property, or HTTP Header and even compare it to mobile browsers.
These detailed pieces of information are called BCD keys. When grouped together, they form web-features that show you support for general features in less granular detail.
Web-features are also available with Baseline status under the web_features category section of the site.
Additionally, CanIWebView offers written documentation on WebView behaviours and differences that is documented here.
