> ##### Note!
> You cannot use both layout-boxed and layout-navbar-fixed or layout-footer-fixed at the same time. Anything else can be mixed together.
{: .quote-danger}
AdminLTE 3.1 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.
- Fixed Sidebar: use the class `.layout-fixed` to get a fixed sidebar.
- Fixed Navbar: use the class `.layout-navbar-fixed` to get a fixed navbar.
- Fixed Footer: use the class `.layout-footer-fixed` to get a fixed footer.
- Collapsed Sidebar: use the class `.sidebar-collapse` to have a collapsed sidebar upon loading.
- Boxed Layout: use the class `.layout-boxed` to get a boxed layout that stretches only to 1250px.
- Top Navigation: use the class `.layout-top-nav` to remove the sidebar and have your links at the top navbar.
##### Responsive Variations
You can also use the following classes for responsive changes with placing
- Fixed Navbar:
- use the class `.layout-*-navbar-fixed` to get a fixed navbar.
- use the class `.layout-*-navbar-not-fixed` to get a not fixed navbar.
- Fixed Footer:
- use the class `.layout-*-footer-fixed` to get a fixed footer.
- use the class `.layout-*-footer-not-fixed` to get a not fixed footer.
> ##### Tip!
> If you want to use anchors with a fixed navbar, you need to add `.anchor` to you hidden anchor, e.g. `<a id="testAnchor" class="anchor"></a>`.
>
> To get a smooth scrolling to the anchor you need to add `.scroll-smooth` to your HTML tag like this `<html class="scroll-smooth">` otherwise it jumps directly to your anchor, `.scroll-smooth` can cause issues with a Chrome extension called ScrollAnywhere.
