Creating Simple Attributes
This is a simple demo showing how to add the title and class attribute using code.
It switches between warning/primary depending of the second being odd or even. Refresh the page to see the difference.
If you mouse-over, you'll also see the tooltips showing stuff which would cause trouble otherwise. 

<div @Tag.Attr("title", titleWithIssues) 
  @Tag.Attr("class", cls)
  @Tag.Attr("number", 27)>
