How does CSS work? When a visitor loads one of your Web pages, by either typing in the address or clicking a link, the server (the computer that stores the Web page) sends the HTML file to the visitor’s computer along with any files linked to or embedded in the HTML file. Regardless of where the CSS code is, the visitor’s browser will interpret it and apply it to the HTML to render the Web page using that browser’s particular rendering engine that is then displayed in the browser window. All modern browsers (Internet Explorer, Firefox, Safari, Opera) support CSS2 (which includes CSS1 and CSS-Positioning). However, after years of development, CSS3 remains a work in progress, supported by some browsers (Firefox, Safari, and Opera) but still under development in others (Internet Explorer)
