So I have a helper method that I am trying to apply css to without putting it in a div or any other element. How would I go about applying the css class to this helper in rails?

I tried:

```
<%= first_letter_content(e.content), :class => "first-letter" %>

```

and

```
<%= (first_letter_content(e.content), :class => "first-letter") %>

```

both resulting in `syntax error, unexpected ',', expecting ')'`

Helper code:

```
def first_letter_content(content) 
  first_letter = content[0] 
  return first_letter 
end

```

Any suggestions? I have been trying to find the proper syntax, but no luck.
