This code displays a message if it exists, but when it does not exist, displays a white line:

<%= if @comprovante["transacao"]["complemento"] do %>OBSERVACAO: <%= @comprovante["transacao"]["complemento"]%><% else %><% end %>

how do I not display this blank line?

The blank line that is being displayed is Else condition and as it has nothing is returning nil, which makes it a blank line, to avoid just remove the Else or put a return to the same.

<%= if @comprovante["transacao"]["complemento"] do %> OBSERVACAO: <%= @comprovante["transacao"]["complemento"]%><% end %>
