I usually type up the content on my pages and posts in word before pasting them into the 'visual' box on WordPress and posting them. However because I must use different fonts every time I've used Word I've ended up with a website full of different fonts. I thought WP automatically changed them to a standard font but it seems not.
How do I change it all without having to copy and paste all the posts and pages back into Word, make them the same font and size, before pasting them back into WP? I'd prefer not to mess around with the code of the theme if possible.
