I'm just tweaking my site. http://www.hackneytools.com, and I already have a child theme running. I'd like to adjust
the width of the slider on my home page, so that the background images don't get tiled. As I understand it from
the forum, I can edit the functions.php in my child theme, but I only have a main stylesheet, (in bold) file listed,
and an 'rtl.styelsheet', unlike the main theme folder, where I have loads of items.
Can you tell me how I create a 'functions'php' file here please? Or, if I've done something wrong, how I refresh
the child theme so I get the full list?
