Only one column instead of two after "big post"

Hi,

I would like every post to look like the first one under the header instead of being divided into two different columns.

Have anyone done this and would like to share how its done?

Thanks!

Hey there,
I hope you’re doing well today

This is apart of the theme design, changing this would require some amount of CSS changes.
Customizations to this degree which modify or extend the item beyond the original features, style and functionality described on the item page is beyond the scope of support that can be provided.
