Highlight / color all input fields

I've figured out how to 'highlight/color' most all of the input fields using the following CSS.

input {background-color: #FFFFCC !important;}

textarea{background-color: #FFFFCC !important;}

select{background-color: #FFFFCC !important;}

However, I'm not able to figure out how to do this for the radio buttons.

Lastly, I used the following CSS to highlight the signature boxes, but they only look right in the Build Mode. They do not show in the Preview Mode.

.signature-pad-passive {background-color: #FFFFCC !important;}

I appreciate your assistance:).

If you mean the background of the unselected option, use the below custom CSS codes:

.form-radio-item:not(#foo) label:before {

    background: #FFFFCC !important;

}

For e-Signature, try this:

canvas.jSignature {

    background-color: #FFFFCC !important;

}

AWESOME!!!! Thank you Welvin!
