Layout
Tips
The starter page is a good place to start building your app if you’d like to start from scratch.
The layout consists of five major parts:
- Wrapper 
.app-wrapper. A div that wraps the whole site. - Main Header 
.app-header. Contains the logo and navbar. - 
                Main Sidebar 
.app-sidebar. Contains the sidebar user panel and menu. - Content 
.app-main. Contains the page header and content. - Main Footer 
.app-footer. Contains the footer. 
Layout Options
              AdminLTE v4 provides a set of options to apply to your main layout. Each one of these
              classes can be added to the
              body tag to get the desired goal.
