Change border color the main form and fields

Hello - I am working on a form. The fields have a green border around them and I cannot get them to change. How do you change the border color of the field frames - as well as the main border on the form? 

thanks.

Thank you for reaching support,

I made some customizations and here is a screencast:

If that is acceptable, please insert the following codes into your Inject Custom CSS area: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

.form-all {

    border: none !important;

}

.form-all input {

   border-width: 2px !important;

   border-color: #828282 !important;

   padding: 4px 3px 2px 3px !important;

}

textarea#input_16 {

    border-width: 2px !important;

    border-color: #828282 !important;

    padding: 4px 3px 2px 3px !important;

}

I hope that helps.

Best.
