Change Font Size in Posts

Look in style.css of your theme.

How do I change the font size in the body of al my posts? Yes, I know I need to look in style.css but there is no tag for changing body text size. any help?

link your site?

sometimes, if the tag is completely missing, you need to add it, to specify the size.

like
body {font: 62.5%/1.3 verdana, 'Lucida Grande', arial, sans-serif; background:#fff; color:#111;}

see is this solves it.

Thanks

That worked
