I'm trying to customize an AddThis button for a text widget for my blog. The addthis.com website states this is possible and gives instructions, however, I can't seem to figure out how to get it to work. http://addthis.com/pages/gallery-demo-addthis-icons-32x32 <---- this is the link that will show the option I want. It mentions adding CSS and HTML, but I'm not sure where and how. Yes, I have the CSS upgrade Any help would be appreciated!
The blog I need help with is imaprile.com.
