Is there a way to execute code in blazor component inside html tags?

Question

What I am would like to do is something like this:

<input type="text"
@if(!String.IsNullOrEmpty(Element.Placeholder))
{
   placeholder="@Element.Placeholder"
}
/>

And I want to do that with many properties like maxlength, value etc. The best solution I came up with is using MarkUpString to do the above and then render it. I was wondering if there is a way to use if's inside an html tag so my code will be cleaner and easier to modify. Please be lenient, I'm new to programming and especially Blazor. Thanks

*Edit: I want this component to be editable from another component too.

You can use @attributes. I've shown a very simple code example below setting the style.

<button @attributes="this.ButtonAttributes">Red Button</button>

@code{

  private Dictionary<string, object> ButtonAttributes = new Dictionary<string, object>();

  protected override Task OnInitializedAsync()
  {
    ButtonAttributes.Add("class", "btn btn-danger");
    return Task.CompletedTask;
  }

}
