Forum: Rails Spinoffs (closed, excessive spam) del.icio.us tag

in del.icio.us header, when i typing a word, the input box is resized.

is there any thing similar in prototype/script.aculo.us?

It looks like they are doing something like this:

Event.observe($('field'), 'keyup',function(e){$('field').size = 40+
$F('field').length*11;});

try this:

Event.observe(
  $('tag'), 'keyup',function(e){
    $('tag').style.width = (30 + $F('tag').length * 4) + 'px';
  }
);

Why 4?
