This will easily done with jQuery

<script>
    $(document).ready(function(){
        $("#btn").click(function(){
            $("#para1").slideToggle(400);
        }
    });
</script>

True, but why include a 32Kb script just for those 12 lines?

My posting jenious, i'm not right person to tell you because you knows every thing. If he want some smooth handling then he'll use it And also it will help for other things like validating, loading a pages..

Is there any reason why would I want my toggle to take longer than a click to get out of my way and pop up right back when I need it?
- Or, what gives me the right to punish my client's bandwidth with additional 92KB download and leave him hanging, before he could toggle it back and forth with that document ready thing, and for what? A thing of which my client doesn't have the slightest interest and moreover, doesn't even notice!

Aside that, your reply is hostile and uneducated. And I don't like it; At all.
