With the Gravity Forms 1.5, we were introduced to "Ready Classes". Now, these classes come with a set of exceptional features that are hard to ignore. When you are creating forms for your pages, these ready classes can give you the capability to build some unique looking layouts that give a different look and feel to the field in the forms. In its truest form, Ready Classes can be defined as those class names that can be assigned to the parent elements around every field. What it does is that it makes use of the default styles that are contained in the stylesheet for the forms.
