I'm currently trying to add an icon to a text box in mvc5. I'm quite new to asp.net and I can't figure out how to do it. I would usually just use `<i class="fa fa-icon"></i>`. 

Within the input area, however I have:

```
@Html.TextboxFor(m=> m.EmailAddress, new {@placeholder = "Email Address"})

```

Any help would be greatly appreciated.
