Switch linked metafield products from Vertical To Horizontal

[rebbin]

Hello,

Im using metafields on our shop to show and link to alternate colors of products. Since my last theme-update the products show in a vertical row instead of horizontal as showed on my pictures.

Can anyone help me switch from vertical to horizontal again. Theme is Impulse.

HTML Code used in custom block:

{%- if product.metafields.custom.alternative_products.value -%}
  <p><strong>Finns även i dessa färger</strong></p>
  {%- for alt_product in product.metafields.custom.alternative_products.value -%}
    {%- if alt_product.available -%}
    <a href="{{ alt_product.url }}" title="{{ alt_product.title }}"><img src="{{ alt_product.featured_image | img_url: '90x90', format: 'pjpg' }}" alt="{{ alt_product.title }}" loading="lazy"></a>  
    {%- endif -%}
  {%- endfor -%}
{%- endif -%}

Thanks!
