9CBS Blog's skin, I prefer Congnition. But always feel that the words in the article are smaller, unhappy.
So the CSS file is now analyzed, find the method: add to the custom CSS selector
Div.posttext {padding-right: 10px; padding-left: 3px; font-size: xxxpt; padding-bottom: 3px; padding-top: 3px;}
Where XXX is the font size, the default is 8, I changed to 10.
