Show the variables as is

This uses the basic @variableName syntax. This will result in encoding html, so tags in that variable will be shown as html-source.
  • this is text, it doesn't have tags
  • this string <em>has</em> html <strong>tags</strong>

Encode using @Html.Raw(...) or @:...
  • this is text, it doesn't have tags
  • this string has html tags
By the way: if you're only working on newer DNNs like 9.x, you can also use @:... as a shorter version of Html.Raw

Reuse a Snippet using @helper

Razor Helpers are like functions, which you can call again and again to produce html. What makes them special is that you can write html into the function, just like normal razor code.

  • this is text, it doesn't have tags
  • this string has html tags
  • this is just a bold line
