The light blue is sometimes hard to see and I'd like to use a darker color if I can! I know there's a code for everything out there so I'm sure someone has figured it out XD Also, if there's potentially a code to thicken the outline too, that would be much appreciated!

EDIT: I actually found a CSS guide that's absolutely amazing and had the code I needed! .wishlist {border: 1px solid ;}

Although I changed it to just be .wishlist {border: 2px solid}
