Instance Level configuration allows you choose how you want it every time you call "NewCssCal" function. On the other hand, file level configuration applies to all "NewCssCal" instances in a web page.
You will be able to find a block of variables in the first one hundred lines of code started with "Configurable parameters - start" and ended with "Configurable parameters - end".
What circled in purple are parameters that you can customize to suit your own needs. The first half are color parameters that you can set and the other half are non-color parameters that you can play around with.
What appeared in the picture may not be what you have downloaded. As the program evolves, parameters might be added or removed, the picture above is only for illustration purpose.
//Configurable parameters - start
var SpanBorderColor = "#000000";//Calendar border color
var MonthYearColor = "#cc0033"; //Font Color of Month and Year in Calendar header.
var WeekHeadColor = "#18861B"; //Background Color in Week header

var UseImageFiles = true;//Use image files with "arrows" and "close" button
var imageFilesPath = "images/";//Path of date time picker image files relative to HTML page
//Configurable parameters - end
Besides customizing the appearance of the calendar, language of the calendar is also not hard coded. You can change the Month and Week name to your preferred language.
You may just locate the global array variable "MonthName", "WeekDayName1" and "WeekDayName2" and replace it in your own language.
//use the Month and Weekday in your preferred language.
var MonthName = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var WeekDayName1 = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
var WeekDayName2 = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];
I tried as much as I can to explain the purpose of the parameter by tailing a comment on each of the variable. If you still do not understand or you happen to detect a bug, please email us.
