Hello Kenneth,
thank for your post.
I would say "succeded to do what ?"
Each template have its own advantages and inconvenience, depending on what is the need
For list templates, it's totally in function of the view you need.
Effectively, the template seb_blog need to be updated, to be more responsive.
But instead, you can use the seb_list which more simple.
After that, for the content, or item view you can use the seb_minima and create your own layout by using the plugin field "DIV" around your other fields.
On other solution is to work with Position Override and Variation, so you can do exactly what you need.
it is a strength of SEBLOD to have not a single solution, but multiple solutions for each case
Best regards.
Lionel
