Text area width unassigned

Text area has no width limit in style.css. That causes scaling problems when using webforms as blocks or pages.

Current code:

.form-textarea-wrapper textarea {
  border-radius: 3px;
  border: 1px solid #acacac;
}

.form-text {
  border-radius: 3px;
  border: 1px solid #acacac;
  padding: 4px 5px;
}

Must be:

.form-textarea-wrapper textarea {
  border-radius: 3px;
  border: 1px solid #acacac;
  max-width:100%;
}

.form-text {
  border-radius: 3px;
  border: 1px solid #acacac;
  padding: 4px 5px;
  max-width:95%; /* text-fields to fit borders */
}
