thanks, I actually did work it out horray!
I think i found the right place in
In the files I went to public_html/wp-content/themes
Then found the child theme I had made. Then went to style.css when I opened this a notepad came up. I have previously copied and pasted the changes into here directly from the inspect element but then nothing happened. Do I need to upload it? or did i copy the wrong information?
thanks
thanks Swayam, for the reply but how do I do that?
