Buy it now button

[tourbrandus]

Hello, I am trying to remove this white outline around the buy it now button. I added the black outline and want it to be filled in. 

Also does anyone know how to change the "buy it now" to all caps?

Hello There,

1. In your Shopify Admin go to online store > themes > actions > edit code
2. Find Asset > base.css and paste this at the bottom of the file:

.shopify-payment-button {
border: none; /* Remove the white outline */
color: white; /* Set the button text color */
text-transform: uppercase; /* Convert text to uppercase */
}

Hi this did not work for me. 

I already have a black border that I want to keep.
