Vertically align the text of each cell

Question

I would like to know if there exists a technique to make the text set at the same line or at the same level because what I did is to add a line-height for my two first blocks but if I add a line-height for the others there is still a difference. It creates a weird look because my titles are not the same in each cell.

$(document).ready(function() {
  $(".toggler").click(function(e) {
    e.preventDefault();

    $(this).closest('table').find('[class^="cat"]').toggle();
  });
});

a {
  color: #002642;
}

.center {
  text-align: center;
}

.toggler,
.cat1 {
  font-family: 'Varela Round';
  color: white;
}

td {
  display: block;
  width: auto;
  border: 1px dotted #c4a77d;
  background-color: #c4a77d;
  color: white;
  margin-bottom: 10px;
}

@media only screen and (min-width: 70em) {
  td {
    display: table-cell;
    border: 1px dotted #c4a77d;
    background-color: #c4a77d;
    color: white;
    margin-bottom: 0px;
  }
}

p {
  font-family: 'Varela Round';
  font-weight: bold;
  text-align: center;
}

Answer 1

All you need is vertical-align:baseline on the table cells. td elements have vertical-align:middle by default.

$(document).ready(function() {
  $(".toggler").click(function(e) {
    e.preventDefault();

    $(this).closest('table').find('[class^="cat"]').toggle();
  });
});

a {
  color: #002642;
}

.center {
  text-align: center;
}

.toggler,
.cat1 {
  font-family: 'Varela Round';
  color: white;
}

td {
  display: block;
  width: auto;
  border: 1px dotted #c4a77d;
  background-color: #c4a77d;
  color: white;
  margin-bottom: 10px;
  vertical-align:baseline;
}

@media only screen and (min-width: 70em) {
  td {
    display: table-cell;
    border: 1px dotted #c4a77d;
    background-color: #c4a77d;
    color: white;
    margin-bottom: 0px;
  }
}

p {
  font-family: 'Varela Round';
  font-weight: bold;
  text-align: center;
}
