I have some content in the module INSET on HP: http://silvarium2.setrnedrevo.cz/
Module INSET has set postion on the right of main content.
When I try view this site on mobile view - with is smaller than 640px, content from INSET module is shown below, but on the right of the main content column remains blank column, which narrows main content.
It is possible to correct this behavior in CSS?
