Removing border color?

How do i get rid of the border color on these number fields:

I tried this: border : none !important;  but it still shows a faint light blue border.

Try this one:

#input_37, #input_68, #input_40, #input_43 {

  border: none !important;

  box-shadow: none !important

}

It should remove the thin border line that surrounds your number fields. I am not sure if that covers everything though. 

Let us know if that works.
