text area problem

[roelof]

Hello,

I made this text-area.
<div class="field">
    <%= f.label :content %><br />
    <%= text_area :content, :nil, :cols=>20,:rows=>5 %>
  </div>

But now the user can make it bigger and smaller.
Can a text-area be a fixed length and width and when the text is bigger you will see a slider?
