I just installed concrete5 and wanted to customize the css file to match the color scheme of my business. Unfortunately, I can't find the CSS file for any of the templates. Unlike Wordpress, it isn't simply a style.css file located inside the theme folder. This is what the page source looks like:
<link rel="stylesheet" media="screen" type="text/css" href="/concrete/index.php/tools/css/themes/solutions/main.css" />
I get lost at index.php. I'm not familiar enough with php to understand how a file (index.php) can have sub-folders underneath it.
Thanks for the help.
