change text line width in input form field

Text in the field gets covered because the icon is in the background which doesn't look good. How can I add spacing in input/textarea form fields? I do not want to limit number of characters.

css

.field:invalid {
  outline: none;
  border: 4px solid #EB5757;
  color: #EB5757;
  background: url("icons/error.svg") no-repeat 95% 50% #FFFFFF;
}
