Hide the Default Sidebar
The default sidebar shows up on all of your website's posts, archive pages, search results pages, and pages with the Blog template. If you want to hide the sidebar from any or all of these types of pages, insert the following code into your Custom CSS:
Posts
.single-post #page-sidebar {
display:none
}
.single-post #page-single>.row>.col-md-9 {
width:100%
}
Search Results
#page-search #page-sidebar {
display:none
}
#page-search>.row>.col-md-9 {
width:100%
}
Archives
#page-archive #page-sidebar {
display:none
}
#page-archive>.row>.col-sm-9 {
width:100%
}
