"display: table-cell" has no constistent alignment - html

Question

Once between the div tags, an HTML tag (eg headings, breaks), the contents are no longer align the same. Example: Html.DisplayFor (...) should end always justified. How can this be fixed?
<div class="table">
<div class="row">
<div class="cell">
<h3>Heading 1</h3>
<hr />
<div class="row">
<div class="cell">Label 1</div>
<div class="cell">Html.DisplayFor(...)</div>
</div>
<div class="row">
<div class="cell">Label 2 with much more Text</div>
<div class="cell">Html.DisplayFor(...)</div>
</div>
<br />
<h3>Heading 2</h3>
<hr />
<div class="row">
<div class="cell">Label 3 with Text</div>
<div class="cell">Html.TextBoxFor(...)</div>
</div>
</div>
<div class="cell">
...
</div>
</div>
</div>
CSS:
div .table {
display: table;
width: 100%;
}
div .cell {
display: table-cell;
padding: 0.3em;
}
div .row {
display: table-row;
}
It should actually look more like this (red line):

Answer 1

Its because you break the flow of the layout by not adhering to only using a table->row/cell structure but by injecting div and hr elements in the middle of it.
You could simply add a width to the first column:
.row .cell .row .cell:first-child{
width:200px;
}
