I am working with an uplouad plugin for a jquery file that has its own CSS files, but when the plugin is implemented on a web page, it also has its own CSS file, the elements will have styles applied from several files, so I need a tool that allows me to select a CSS file and an HTML file, than the tool should show all the elements affected by this file, I used Firebug, but it only provides the opposite of what I need, for example, select an element and see that all CSS files affect the element, I think that longer n be a faster way to do this.
