Blog Layout responsive/dynamic

Hi,

I use the three column Blog layout on my page. This looks fine at screen size bigger than 1200px width.

On mobile phones the layout becomes either to one colum + 1 sidebar or to one single column.

Is there a way to have a two colum based blog with 2 sidebars around 1024 px width?

my site is: https://www.st-johannes-ap.de

Thanks for help

Daniel
