Is there a way to clear after the last element of a row without a wrapping container per row? The column sizes inside will vary, there is a 'last' class, can I clear after that div is closed? I can't add anything to the markup.
Markup:
<div class="grid-row">
<div class="col-6">
col 6
</div>
<div class="col-6 last">
col 6
</div>
<!-- Need to clear here -->
<div class="col-4">
col 4
</div>
<div class="col-4">
col 4
</div>
<div class="col-4 last">
col 4
</div>
<!-- Need to clear here -->
</div>
