title: slim-lang's if-else nested code
body: <p>I want to assign a css class to a part of HTML based on condition in slim-lang</p>
  
  <p>I am doing the following</p>
  
  <pre><code>- if current_user
    .title
  - else
    .title_else
  </code></pre>
  
  <p>Now how can i write the HTML that should be nested in the one of the class above? Do i need to write HTML in the both <code>if</code> condition and <code>else</code> condition ?</p>
  
  <p>The reason is that the HTML that should be nested in one of the above class should be further intended rightwards. But if i intend it further right, it is including under else condition. How shoule i approach this now ?</p>
