Place a css class in a div using MVC and Razor

Question

I have used following code to add css class:

<div id="123" class="tab-pane @{ if (some_condition) { Html.Raw("active"); }; } ">

But it did not work.

I hope for this result:

<div id="123" class="tab-pane active">

@MichaelPerrenoud's answer is close. You need to wrap the whole conditional in parenthesis.

Using @() tells razor to output a string. So

<div id="123" class='tab-pane @(condition ? "active" : "")'>
