ruby on rails - Styling a form_tag -

i have following form:

  = form_tag '/posts', {id: "link-form"}     = text_field :post, :link     = submit_tag "add link", {id: "submit-button"} 

, renders:

<form accept-charset="utf-8" action="/posts" id="link-form" method="post">     <div style="margin:0;padding:0;display:inline">         <input id="post_link" name="post[link]" type="text">          <input id="submit-button" name="commit" type="submit" value="add link">  </form> 

it seems rails automatically add div in second line: <div style="margin:0;padding:0;display:inline">

this div inherits parents, , can't access div (such assigning id) change appearance.

how can access div, or how go around it?

its div hidden inputs existing data. not have touch it.
