In the previous parameter you selected a style for control panel. Here you have the option to adapt it to your specific needs. Just indicate here the name of the file that contains the css (cascading style sheet) that will overwrite the current style.<br>
This file can be in the directory of the application (www.net2client.com/ZZZ/BD/EE/EEE). If that is the case, just write the name of the file (Exp. companystyle.css) or for any other internet file, just write the URL (www...). To find the original style, download the file www.net2client.com/sis/estilos/arribaX.css where X is the number of the style selected in the previous parameter.
