This isn't Rails-specific, and I'm sorry for that, but I haven't been
able to get a response in the #prototype/#javascript/#ror channels,
nor find anything via Google.

I have a form element that I want to be hidden when the page first
loads, and appear when a user clicks the link.  Here's the code:

<div id='signin-link'><%= link_to 'Sign In', '#', :onclick =>
"'signin-form')"  %></div>

<div id='signin-form'>
  <%= start_form_tag(signin_url)%>
    <%= text_field_tag :username %>
    <%= password_field_tag :password %>
    <%= submit_tag 'Sign In' %>
  <%= end_form_tag %>

In my CSS file I have
#signin-form {
  display: none;

Now checking out, I'm
pretty sure that's all I have to do.  However if I click on the link,
the form doesn't get shown.  No JS errors.  If I have the element
shown at the page start, I can hide/toggle it all I want.  Just can't
start off with display:none apparently.  I'm using Firefox 1.5.01 and
the javascript files that were installed with "rake rails:update".

Try it with the style embedded. i.e:

<div id="signin-form" style="display:none">

I'm not sure what difference that would make, but that's what works for

If you set display: none in the CSS file, Javascript won't realize it.
have to manually specify style="display: none;" in the HTML.

Cool, that works, thanks for the help.

The difference is that "display:none" in external CSS overwrites
the browsers default for the display attribute, which is (for most
either "block" or "inline", whereas setting it on the "style"
attribute you
can fall back to the browsers default later (which is what does).

That's a bit of an annoyance with the CSS spec, that it doesn't seperate
how an element should "flow" on the page from whether it should
be displayed at all.
