Сервировка CSS: почему строка таблицы не принимает поле?

.container {
  width: 850px;
  padding: 0;
  display: table;
  margin-left: auto;
  margin-right: auto;
}
.row {
  display: table-row;
  margin-bottom: 30px;
  /* HERE */
}
.home_1 {
  width: 64px;
  height: 64px;
  padding-right: 20px;
  margin-right: 10px;
  display: table-cell;
}
.home_2 {
  width: 350px;
  height: 64px;
  padding: 0px;
  vertical-align: middle;
  font-size: 150%;
  display: table-cell;
}
.home_3 {
  width: 64px;
  height: 64px;
  padding-right: 20px;
  margin-right: 10px;
  display: table-cell;
}
.home_4 {
  width: 350px;
  height: 64px;
  padding: 0px;
  vertical-align: middle;
  font-size: 150%;
  display: table-cell;
}
