Wp Forms Labels not showing

It is currently under construction.

I’m trying to change the WP Forms labels so they will show. I’m trying to make them black. So I add this in to my css but it doesn’t change

div.wpforms-container-full .wpforms-form .wpforms-field-label {
color: #000;
}

But if I had that line in Web Developer Tools in the same section it changes the color for me.

What am I missing?
