CSS to customize the opinion scale text:
.ss-answer-option--rating label {
display: none;
}
.ss-answer-option--rating::after {
content: "";
position: absolute;
top: 100%;
margin-top: 10px;
color: gray; /** Change label color **/
}
.ss-answer-option--rating:nth-child(1):after {
content: "First";
}
.ss-answer-option--rating:nth-child(2):after {
content: "Second";
}
.ss-answer-option--rating:nth-child(3):after {
content: "Third";
}
.ss-answer-option--rating:nth-child(4):after {
content: "Fourth";
}
.ss-answer-option--rating:nth-child(5):after {
content: "Fifth";
}
.ss-answer-option--rating:nth-child(6):after {
content: "Sixth";
}
Here we can replace the text which are under double quotes. For example, it can be replaced with a text "First" with "Negative" or anything.
Also, the same format can be followed for the next scale which is added for the question.
