I found the thread on making the fields taller but it is closed to discussion so posting here. I added this code
.gform_wrapper input, .gform_wrapper option {
height: 3em;
}
and it worked but for the multiple choice radio button, they get out of align.. Does anyone know how to fix this? I would like to use the 3em for the height of the fields and keep the multiple choice radio selections in alignment.
