I recently installed MarketPress and am having a surprisingly hard time changing its look to match my site. I am already using an unrelated theme that I like and would like to set up a pretty simple store on pages within that theme. The basics seem to work, but there are some style issues that I'd like to fix and I can't see exactly where I'd go to make these changes. (I am not a PHP or CSS expert so I would like to start with the existing style(s) and modify.)
So, where do I find the file locations that define the following things I want to change:
1) In the classic, modern, or icons style the "add to cart" buttons change size when moused over (become slightly taller and narrower). The CSS files in marketpress-includes/themes show the exact same CSS for both states so behavior this must be coming from somewhere else?
2a) The default shopping cart at /store/shopping cart has "quantity" as the widest field. I would like to reformat the table so this isn't the case.
2b) The Quantity field accepts any character and enormous order numbers. If you enter a letter first in the quantity it empties the cart. I assume this is a bug? Where is this field defined so I can add some input validation?
3) The shopping cart widget is too wide for the sidebar on my site. Where is its format defined so I can attempt to reformat and get it to fit properly?
Thanks in advance!
