Layout row class

I need a way to identify the type of layout row e.g 1/2 1/2. I know I can use $layout->id() , but this is a random string unique to each layout. Is this possible?

 <?php foreach ($page->features()->toLayouts() as $layout): ?>
 <div class="flex flex-wrap md:-mx-3  layout-<?= $layout->id() ?>">
     <?php foreach ($layout->columns() as $column): ?>
     <div class="w-full sm:w-<?= $column->span() ?>/12  pb-[39px] md:px-3 ">
         <?= $column->blocks() ?>
     </div>
     <?php endforeach ?>
 </div>
 <?php endforeach ?>

I managed to sort this with just css
