Is it possible to add rules or grid to the form 2.0 editing mode?

I recently had to modify a button on my form so it aligned with the fields better. A little CSS code knowledge is useful.
In form settings > Form theme > edit custom CSS add this code and then alter the position as you need. Obviously you will need to change  "left" to "right". You can also get rid of any color, height and width info that doesn't work for you. - hope this helps.

/* Add your custom CSS below */

.mktoButton {
  -webkit-appearance: none;
  background-color:#f18100;
  position: absolute;
  left: 0px;
  height: 54px;
  width: 443px;
  color: #fff;
  font-size: 40px !important;
  font-weight: 600;

}

.mktoButtonRow {
  width: 443px !important;
}

.mktoButtonWrap {
  margin-left: 20px !important;
  width: 443px !important;
}
