When you created your Contribution/Donation button in the LaterPay Button Generator, you were sent an email with the code for the button and a link. The code for the button includes the inline CSS directives to give this link it’s button-like appearance and color. If you want to change the color of the button, carefully change this part of code:“background-color:#01a99d !important”. You will need to replace the color with a valid CSS value.
If you want to change the color of the text in the button, look for towards the end of the Button code “style="text-decoration:none !important;color:#fff !important” and change color:#fff to the hex value you want.
