I do apologise for what appears to be a straightforward question but I just cannot get the hang of the use of the child theme :-(
I have followed the instructions on your site and read the WordPress page on child themes and this is what I've done
1. I have created a Luminescence Lite child folder in the themes folder and it shows in my list of installed themes as you suggested.
2.I have copied the following from the style.css of the main theme
background: #1d2022 url('images/backgrounds/background1.jpg') 0 0 repeat fixed;
font-family: Arial, Helvetica, sans-serif;
3. I activated the child theme and pasted the above into the style.css of the child theme and changed
font-family: Arial, Helvetica, sans-serif; to font-family: Georgia, serif; I may want to change other body style elements hence the reason I copied the whole body code.
4. This changed the font in the child theme but when I then activated the main theme where all my design changes are eg colour background etc, the font is still the original?
I realise that you recommend a knowledge of css files which I haven't got (and it's probably a bit late in the day for me to start learning that at my age) but having followed what I thought were clear and precise instructions I still don't get it? Can you help?
I appreciate any help you can give me.
