joomla events templates

pls how and where do I:
1. reduce the spaces between the module positions
2. change the font type, size and color?

the url is cipmglobal.org
thank you.

I also wants to change the page background

Background can be changed form template parameters , check in template manager then select events template.

For module distance in layout.css:

.module_padding {
padding: 0;
margin: 30px 20px;
float: left;
}

reduce margin values
