Can you give me the css code to add in order to make these actions:

The bin in cart is to dark we can’t see it, can you make it white like the text color
Same for the numbers in the opc steps: 1, 2 and 3 they are darker and can’t see it

ALSO, in the second prinscreen, you can see that when I am on the button we cannot see the text anymore, can you make the texte white when hover mouse?
thanks
