GF Signature field blank in Divi not working despite adding custom css please help

[user6699ca1d8b4d2153 (Drex Dobson)]

I tried adding this in the custom css field; didn’t work.

Blockquote
#input_27_12 {
width: 65vw !important;
}

Blockquote

I tried adding a width, color of pen, border color, etc., and all it displays is a blank field. GD is confirmed on and working.

Please help. Latest divi/GF/sig. No caching plugins, etc.
