The layout consists of four major parts:

- Wrapper `.wrapper`. A div that wraps the whole site.
- Main Header `.main-header`. Contains the logo and navbar.
- Main Sidebar `.main-sidebar`. Contains the sidebar user panel, search form and menu.
- Content `.content-wrapper`. Contains the page header and content.

#### Layout Options
{: .mt-4}

> ##### 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 3.2 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.

#### Preloader

Preloader to avoid [https://github.com/ColorlibHQ/AdminLTE/discussions/3319](https://github.com/ColorlibHQ/AdminLTE/discussions/3319)

```html
<div class="wrapper">
  <!-- Preloader -->
  <div class="preloader">
    <img src="dist/img/AdminLTELogo.png" alt="AdminLTELogo" height="60" width="60">
