Hi! I'm hoping to find the answer to this question too. I would like to replace the words "quick view" with my own text, "Add-on".
I'm using this css:
.sqs-product-quick-view-button-wrapper .sqs-product-quick-view-button {
opacity: 0;
content: "ADD-ON"!important;
display: inline-block;
position: relative;
z-index: 6;
width: auto;
height: auto;
padding: 1.4em;
color: white;
background-color: darkred;
border-width: 0;
font-size: 24px;
line-height: 1em;
text-align: center;
}
Everything is working except the content replacement
