Width and colour of fields

Can you post a link to your form for us?

This should do the trick for your field inputs (obviously feel free to use your own Hex colors). Just place in your theme's stylesheet (or wherever you are instructed to place custom CSS at the theme level).

[css]
.gform_wrapper input[type=text], .gform_wrapper input[type=url], .gform_wrapper input[type=email], .gform_wrapper input[type=tel], .gform_wrapper input[type=number], .gform_wrapper input[type=password], .gform_wrapper textarea {
background-color: green;
border: 1px solid blue;
color: #fff;
}

For your paragraph field are you wanting that to be the same width as your inputs above it?

Thanks! sorted!!
