I am helping a client with their website and we used the Buy Button as she already has an existing Wix site and Shopify's website builder did not have the fonts she wanted to use. We added the buy button, but I cannot seem to figure out how to change the colour of the button when an item is sold out. I have tried changing the colour in the code but to no avail. We would also like the button height to be smaller, when changing it with the editor we are only able to change the width. Again, I tried changing this in the code but it is not looking how we want it. Any help would be appreciated.
