Safari CSS Reference: Introduction to Safari CSS ReferenceYou can use Cascading Style Sheets (CSS) in conjunction with HTML-based web content to fine-tune the style of the content. The goal of CSS is to separate the structure provided by HTML from the style provided by CSS. Taking style information out of the structure allows designers to independently tune a page’s style for a variety of audiences and readers (such as desktops, hand-held devices like iPhone, and text-based browsers). All Safari web browsers use the WebKit engine to display webpages. WebKit is an open source framework in Mac OS X that lets developers embed web browser functionality into applications.
