characteristics display front end

hi,

please can you take a look at my shop here
as you can see the different characteristics text is very close together - there's no gap between the different pack quantities. I've tried adding a space after the each characteristic in products>characteristics>please select pack quantity.
however it has not made any difference.

do you know of any way I can change this?
is there also a way to change the picture of the unavailable variants in the table? the X over the circle is a bit faint so I was hoping to change it something brighter

kind regards,
Tanya
