Sayontan, my goal is slightly different: I want to *increase* the padding between the left and right edges of the page and post boxes and the text the content contains, only without doing the adjustments in h1, h2, etc (because that messes up my columns). The solution above works for my pages (
http://octav.net/your-story-isnt-told-by-you/ ), but not for my posts (
http://octav.net/ ). Any suggestions for a streamlined approached that works for pages and posts alike? I've visited the "hook reference" you've directed me to in the past (
