Different width for columns in a dnd-template

Good afternoon,
when creating a dnd-template in the design manager a width attribute can be given to the element. But if I want to position two modules next to each other with different widths, this does not work. Each element takes up exactly half of the available space. Where is my mistake?

{% dnd_area 'dnd_area' class='body-container body-container--landing-page', label='Main' %}
 {% dnd_section 
 max_width=1506,
 vertical_alignment='MIDDLE'
 %}
 {% dnd_column
 offset=0,
 width=4
 %}
 {% dnd_row %}
 {% dnd_module path='@hubspot/linked_image' %}
 {% end_dnd_module %}
 {% end_dnd_row %}
 {% dnd_row %}
 {% dnd_module path='@hubspot/rich_text' %}
 {% module_attribute 'html' %}
 <h3>Feature one</h3>
 <p>Use text and images to tell your company’s story. Explain what makes your product or service extraordinary.</p>
 {% end_module_attribute %}
 {% end_dnd_module %}
 {% end_dnd_row %}
 {% end_dnd_column %}
 {% dnd_column
 offset=4,
 width=8
 %}
 {% dnd_row %}
 {% dnd_module path='@hubspot/linked_image' %}
 {% end_dnd_module %}
 {% end_dnd_row %}
 {% dnd_row %}
 {% dnd_module path='@hubspot/rich_text' %}
 {% module_attribute 'html' %}
 <h3>Feature two</h3>
 <p>Use text and images to tell your company’s story. Explain what makes your product or service extraordinary.</p>
 {% end_module_attribute %}
 {% end_dnd_module %}
 {% end_dnd_row %}
 {% end_dnd_column %}
 {% end_dnd_section %}
 {% end_dnd_area %}

@ewice your HubL looks correct from my first glance. It could be an issue with your CSS that’s being used for your layout.css / row-fluid span1-12 classes. Do you have a preview link?

I forgot to link the layout.css.

Thanks
