Laravel use an icon to delete content

I have the following delete button:

{!! Form::open(['route' => ['tasks.destroy', $type->id], 'method' => 'delete']) !!}
{!! Form::submit('Erase this task?', ['class' => 'delete']) !!}
{!!Form::close() !!}

And now I would like to not use a button, but an icon to delete content. I would like to use this button: http://ift.tt/1W8Ql4k

<i class="icon-remove-sign"></i> icon-remove-sign

The sign should be blue and small.

How do I do that? I only get error messages relating to models as a result. But when I dont make any changes it works perfectly.

Can someone give me an example of how to make the picture point to a delete route?
