Thanks

Sorry for the confusion.

We can actually apply the button’s css code on the paypal button. First, we need to see the actual page with the paypal button. If you don’t mind, please post it here.

Thanks!

THank you for using the theme!

First, remove the image on paypal code. It looks something like this:

https://www.paypalobjects.com/en_US/i/btn/btn_cart_LG.gif

Add this on Customizer > Custom > CSS:

form[target="paypal"] input[type="image"] {
display: block;
position: relative;
border: 1px solid #ac1100;
padding: 0.563em 1.125em 0.813em;
cursor: pointer;
font-size: 16px;
font-size: 1.6rem;
line-height: 1.3;
text-align: center;
vertical-align: middle;
color: white;
background-color: #ff2a13;
-webkit-transition: all 0.15s linear;
transition: all 0.15s linear;
margin-bottom: 0.25em;
text-shadow: 0 0.075em 0.075em rgba(0,0,0,0.5);
z-index: 0;
width: 200px;
height: 50px;
}

form[target="paypal"] input[type="image"]:before {
content: 'Add to Cart';
display: block;
width: 200px;
height: 50px;
z-index: 9999;
position: relative;
color: white;
}

form[target="paypal"] input[type="image"]:after {
content: '';
}

I hope that helps.

Cheers!
