How Do I Change the Background Color of a Single Choice Field?

Hello,

I am having trouble getting two fields to change color when I go into the CSS. They are the single choice fields below. It won't let me select just the two white fields but instead selects all the fields on the form. 

I checked your form but I see those Single Choice fields background-color were already gray color.

I think you were able to resolved already. Please let us know if you need further assistance.

Yes and no. I changed the field to two columns and it grayed it out like I wanted. However, I prefer the look of it before, but couldn't get it to work. I'll update the second field back to how it was so you can see.

And just so we're on the same page, when I view it within the Builder, it appears ok. But when I preview it (and embed it) the color disappears.

Please try to inject the custom CSS code below to your form:

.form-section.page-section {
    background : #f2f2f2!important;
}
li#id_678 {
    background: white!important;
}
li#id_597 {
    background: white!important;
}
li#id_738 {
    background: white!important;
}
li#id_691 {
    background: white!important;
}

Please note that you need to change the background color of the other fields to white. The CSS code above will fix the color of the issue you mentioned in your screenshot, but it will also make some white backgrounds to gray.
