As a complete newbie to Concrete5 and indeed any CMS, and as someone with absolutely zero knowledge of PHP, I really need some help here. Is there a document available, free or to purchase, which explains in non-technical language how to edit the CSS across all the pages in my website? I simply want to use different fonts and text colours initially, although if I can work out how to change those I may be a bit more daring. I do have some knowledge of html and css but, as I said, none of PHP.
Thanks in advance to anyone who can point me in the right direction.
