[TheaG]

I have this box: \[code\]<div class="message_box_red" id="commentForm_error_name" style="width: 409px; height: 0px; border: 0; margin: 0; padding: 0;"></div>\[/code\] And I would like to make it animate into this style: \[code\]"border: 2px solid; margin: 1px; padding: 7px; width: 409px;"\[/code\] And then as well insert some text into it, like \[code\]this is a test message\[/code\] or something.
