How to change input background color

How do you change the background color of a field?  Right now, when you enter text, that field turns white.  And having now selected all of the fonts to be white, when I go to enter text into the fields, the text seems to disappear (white text in a white background).  So how do I change the background of the fields? 

Hi,

To do this over Form Designer, just open the Form Designer once you start editing your jotform and then click on the input field. This will give you the options to change the style, including the background in the Form Designer options on the right.

If you would like to inject some CSS code that would do this for you, please give us the jotform that you would like to have this made on, but in general this should work:

input {
   background-color: black !important;
}

Do let us know if you have any further questions.

Best Regards,
Ben
