Hi, Phoca Extensions use external css, but external css cannot be used if there are some parameters which help users to change the style of the extensions via parameters... So if you have the option to style the extension via parameters, then the CSS must be saved in php file...
CSS classes must have other names because more Phoca Extensions can be displayed on the site, and there should not be some conflicts between some extension's CSS...
Because of some non standard webbrowswers which users are using, there must be used CSS hacks and some conditional comments, and and and....
