Today's Web pages or files Magentoshop are partly built in an extremely complex. To work through tens of thousands and thousands of lines, e.g. by: out, which CSS entry for the font color of a page range is, can thus drag on for several hours.
Very simply, it is but the sensible plugin for the Firefox browser Firebug.
This plugin is built right into Firefox and bottom of the browser (usually at the bottom right) symbolized by a small beetle. If you click on a page while it is on these beetles, is a window of the browser to the page recipe book. Here you can find right now, which entry in any jurisdiction in which line CSS file for an appearance is. You can easily change it, to see, what would happen, if something else would.
Firebug makes further proposals, what commands would be used.
So a SUPER useful program for the work of Web developers. There are now even further developments FOR Firebug. These are available from the plugins for Firefox.
Firebug is there right to the Firefox browser (Extras> Add-Ons) or here.
