This file contains routines to edit the optional module files: frontend.css and backend.css
|
|
28
|
Mechanism was introduced with WB 2.7 to provide a global solution for all modules
|
|
29
|
To use this function, include this file from your module (e.g. from modify.php)
|
|
30
|
Then simply call the function edit_css('your_module_directory') - that?s it
|
|
31
|
NOTE: Some functions were added for module developers to make the creation of own module easier
