Spacer
AppBarSpacer is used to provide spacing between the AppBar contents which gives additional space to the content layout.
The following example depicts the code to provide spacing between the home and pan buttons in the AppBar:
@using Syncfusion.Blazor.Navigations
@using Syncfusion.Blazor.Buttons
<div class="control-container">
<SfAppBar ColorMode="AppBarColor.Primary">
<SfButton CssClass="e-inherit" IconCss="e-icons e-home"></SfButton>
<AppBarSpacer></AppBarSpacer>
<SfButton CssClass="e-inherit" IconCss="e-icons e-cut"></SfButton>
<AppBarSpacer></AppBarSpacer>
<SfButton CssClass="e-inherit" IconCss="e-icons e-pan"></SfButton>
</SfAppBar>
</div>
Separator
AppBarSeparator shows a vertical line to visually group or separate the AppBar contents.
The following example depicts the code to provide a vertical line between a group of buttons in the AppBar.

Media Query
Media Query is used to adjusting the AppBar for different screen sizes. Resize the screen to observe the responsive layout of the AppBar.

</div>

</SfTreeView>
</div>
</div>
</ChildContent>
</SfSidebar>
<div class="main-content" id="main-text">
<div class="sidebar-content">
<div class="sidebar-heading"> Responsive Sidebar with Treeview</div>
<p class="paragraph-content">
This is a graphical aid for visualizing and categorizing the site, in the style of an expandable and collapsable treeview component.
It auto-expands to display the node(s), if any, corresponding to the currently viewed title, highlighting that node(s)
and its ancestors. Load-on-demand when expanding nodes is available where supported (most graphical browsers),
falling back to a full-page reload. MediaWiki-supported caching, aside from squid, has been considered so that
unnecessary re-downloads of content are avoided where possible. The complete expanded/collapsed state of
the treeview persists across page views in most situations.
