Cannot see CSS in Flatio Pro

Dear all,

I cannot see any of the CSS for any of the pages I have created in Flatio Pro. I am especially interested in modifying the CSS for the home page so that I can change the icon size, as some others have mentioned wanting to do. But the CSS text word count for that page (and all other pages I created) is 0 (zero)! How can this be? How do I get to see and modify the code underneath the displayed?
