disable color block around field

I've been looking in Design Mode and can't find how to disable the color block which appears when the user selects a field.

See attached image.

I have created a demo form for you here with the highlight effect disabled.

I achieved this by adding custom CSS to the form.

.form-line-active{

    background-color:transparent !important;

}

To add custom CSS to your form you can open your form in the form builder and then click on the preferences button. The preferences window will open and you can click on the form styles tab. Inside of the form styles tab you can type the custom CSS in the text area labeled "Inject Custom CSS".

Good deal.  

Thanks.
