I want to make the size of the font in the body of my posts and pages bigger. I don't want to change the size of the font in the sidebar or footer however. If there a way to do this? I tried going to Post/Page Styling and entering a new font size in Body Box but it had no effect. I know I can change the size in Body, Text, & Links, but that changes the size of the font in the sidebars and footer too. I just want to change the size of the content. Thank you in advance for any help.
P.S. I am using version 3.2 (if that makes a difference). If I upgrade, will any of my changes be lost?
