Form alignment collapses into single row

问题

I have the parent element set to newTableForm with labelColumn and mainFormColumn as children - but with the current CSS everything collapses into one row:

.newTableForm {
  display: grid;
  grid-template-columns: 1fr 3fr;
  grid-template-rows: 30px 30px 30px 40px;
  grid-gap: 10px;
  grid-template-areas: "... main" "labels main" "labels main" "... main";
  border: 2px dashed deeppink;
}

.labelColumn {
  grid-area: labels;
}

.mainFormColumn {
  grid-area: main;
}

<form method='post' action="/admin-post.php" class="newTableForm">
  <h4 class="mainFormColumn">
    Add a new price compare table
  </h4>
  <label for="store" class="labelColumn">Store</label>
  <input type="text" name="store" placeholder="" class="mainFormColumn"/>
  <label for="product-page" class="labelColumn">Product Page Link</label>
  <input type="text" name="product-page" placeholder="Copy address here" class="mainFormColumn" />
  <button class="mainFormColumn">Save new price compare table</button>
</form>

Is there a way to undo the single column stacking behavior here? I would remove the template areas altogether if not for the blank sections with ... (above and below the label section)

Again you can drop grid-template-areas as multiple grid-areas overlap - and you can use pseudo elements for this:

place labelColumn into the first column using grid-column: 1 and mainFormColumn into the second column using grid-column: 2.
after element will be the first column in the last row using grid-row: -2 and grid-column: 1
before will be first column in the first row using grid-column: 1

See demo below:

.newTableForm {
  display: grid;
  grid-template-columns: 1fr 3fr;
  grid-template-rows: 30px 30px 30px 40px;
  grid-gap: 10px;
  border: 2px dashed deeppink;
}

.labelColumn {
  grid-column: 1;
}

.mainFormColumn {
  grid-column: 2;
}
.newTableForm:after, .newTableForm:before {
  content: '';
  display: block;
  grid-column: 1;
}

.newTableForm:after {
  grid-row: -2;
}

<form method='post' action="/admin-post.php" class="newTableForm">
  <h4 class="mainFormColumn">
    Add a new price compare table
  </h4>
  <label for="store" class="labelColumn">Store</label>
  <input type="text" name="store" placeholder="" class="mainFormColumn"/>
  <label for="product-page" class="labelColumn">Product Page Link</label>
  <input type="text" name="product-page" placeholder="Copy address here" class="mainFormColumn" />

  <button class="mainFormColumn">Save new price compare table</button>
</form>

I just update your .newTableForm css with some updates. I hope it'll help you out. Thanks

.newTableForm {
  display: flex;
  flex-direction: column;
  border: 2px dashed deeppink;
}
