It 'a very nice template, only thing I do not understand how you can change the display in Mobile, collapse of the side columns under the article or not display them in the cabinet.

Dear giulian.c,
Because the layout displays from left to right, so left sidebar is above main content, Please add this code to hide it in file: templates/sj-healthmag/css/your_css.css
@media (max-width: 767px){
#content .container #content_left{
display:none;
}
}

Thanks.
