WebKit is an open source browser engine corresponding to gecko (used by Mozilla Firefox etc.) Trident (also known as mshtml ie) and edgehtml (also known as chakra edge and other uwp browsers).At the same time WebKit is also the name of Apple's Mac OS X system engine framework version mainly used for Safari dashboard mail and other Mac OS X programs. WebKit was formerly the KHTML of KDE group. The webcore typesetting engine and jscore engine included in WebKit come from the KHTML and KJS of KDE. When Apple compared gecko and KHTML it still chose the latter because it has a clear source structure and extremely fast rendering speed. Apple carried forward KHTML and launched Safari a browser equipped with the improved WebKit engine of KHTML. 报错
