Custom Code for Font Size

Hi there,

I have a question regarding customization:

1. Where do I input CSS code in case I hire someone to customize the theme for me?

2. I had an email conversation with the Skywarrior theme about changing the font size (and font), whereas it is not a standard option for you. Could you please let me know how I change the font size for blog posts? This was the last reply from your support team via email:

“Hi Ray,

Changing the font size is not something that we generally have as a standard option since it breaks the design in most of the cases. We may be able to accommodate if its a simple change.

Regards,

Thanks guys for the help!
Ray
