A Razor UI component for eyelid effect. It renders a div with class 'eyelids' and binds its CSS opacity to the public float property 'o', and supplies a BuildHash combining that value.
@inherits PanelComponent
<root> <div class="eyelids" style="opacity: @o;"> </div> </root>
@code
{
public float o {get;set;} = 0;
protected override int BuildHash() => System.HashCode.Combine(o);
}
