Styling the mini calendar module

How can I apply a CSS to the mini calendar module? The one in the module folder is an empty CSS file.

Either set the template theme in Config -> themes, or open the theme css files components\com_eventbooking\assets\css\themes. You can change the look there. eg about line 257 for bg color.

What I've done :

1) Using Module Class Susffix -add _ebmystyle
- Extensions Modules Manager-->Ebooking MiniCalendar-->Module Parameters--> Module Class Suffix e.g. _ebmystyle
2) Edit your template
templates/your_template/css/template.css
add your styling e.g.(my example)

/** EbMiniCalendar**/

div.module_ebmystyle, div.module_ebmystyle h3 {
padding: 5px;
margin-left: 8px;
width: 94%;
}
I edited also default.php to add grid to calendar...( /modules/mod_eb_minicalendar/tmpl/default.php)
That's it...
