How do I remove the yellow highlight around selected questions - all other responses seem to be out of date.

I have checked and you have only one form on your account https://www.jotform.com/62224919889269 

Is that the form you are working on? 

I have inspected your form, but I did not saw any yellow highlight around selected field. I also saw that you labels are white so I assume that your form is embedded. If that is the case, please provide us URL of your webpage and if possible a screenshot of yellow highlight. 

You can also try to add this CSS code to your form:

.form-line-active input:focus, .form-line-active textarea:focus {

    border: none;

    box-shadow: none !important;

    outline:none !important;

}

How to Inject Custom CSS Codes

I'm trying to do a transparent background and when I add that code in for the non-highlighted background it has completely messed up the transparent background. Can you let me know what I should do css-wise to have no yellow highlights AND a transparent background?

Thank you for providing us URL of your webpage. Currently background color of your from is not transparent. Please add this CSS code to your form:

.supernova, .jotform-form, .form-all {

    background-color : transparent !important;

}

.form-line-error {

    background-color: transparent!important;

}

After you add this CSS code your form should be transparent and highlight effect should also be transparent. 

And your embedded form should look like this.

Hope this will help. Let us know if you need further assistance.
