Sidebar smooth animation in Blazor Wasm

There isn't to much to detail I'm using the default Bootstrap Template from Blazor Wasm project I just want to know how can I add some kind of smooth animation when closing and opening the sidebar. Here's a small piece of code

<div class="sidebar-nav scroll-sidebar @NavMenuCssClass" @onclick=ToggleNavMenu>
    <Sidebar />
</div>

@* Sidebar Interaction *@
@code {
    private bool collapseNavMenu = true;

    private string? NavMenuCssClass => collapseNavMenu ? "collapse" : null;

    private void ToggleNavMenu()
    {
        collapseNavMenu = !collapseNavMenu;
    }
}

<div class="sidebar-nav scroll-sidebar @NavMenuCssClass" @onclick=ToggleNavMenu>
    <Sidebar />
</div>

@* Sidebar Interaction *@
@code {
    private bool collapseNavMenu = true;

    private string? NavMenuCssClass => collapseNavMenu ? "collapse" : null;

    private void ToggleNavMenu()
    {
        collapseNavMenu = !collapseNavMenu;
    }
}

The trick here is adding and removing the *collapse" class from the navbar div. Thanks!

CSS One class has a negative margin, the other has no margin, add a transition property, done Alternatively animation with keyframes Not much to do with Blazor, besides using it to swap the classes around
