Rails spinoffs - Jun 2007 - Heeeelp: why doesn't Effect.BlindDown work as expected??

Hi all,

First of all: a big hurray for those who have given us Prototype and 
Scriptaculous. Very nice piece of work!

Now, I''ve a bit of a problem with the BlindDown Effect - see [1]. The 
idea is to create a kind of jargon dictionary for terms used in web 
pages. I''d like dictionary to appear as an overlay, in three steps:

a. header appears;
b. the space for the lemma rolls down like a blind;
c. the actual lemma appears;

The a. en c. steps work just fine. The whole process in reverse (upon 
clicking the ''close'' button) looks very smooth, but the
BlindDown in
step b. looks jerky and ugly. And I can''t figure out why!

I''ve spent the entire morning experimenting, and Googling on the web
for
clues. My entire CSS is in-line now, and completely stripped down to the 
bare necessities. Still no luck :(

I''d appreciate any help here, as this is part of a demo I''d
like to have
up and running before the summer holidays kick-in. Thanks in advance.

cheers,
Sandor

Greetings,

        It is a nice piece of work isn''t it?

You''ll want in particular explicit height set to the element so the
effect knows exactly how far it is supposed to blind down.  Check out
the markup on this page to see how objects are styled to deliver
smooth effects.

If you want to see behind the scenes then I''d recommend using Firebug

Sure. Just a few more minor features and scripts get cross browser by 
default.

Trust me, I''ve checked out the usual suspects :) My objects are styled 
with in-line CSS (not classes) trimmed done to the absolutely necessary 
attributes; all the objects have explicit height.

I''ve previously seen jumpy animations, because in-line CSS interfered 
with a class definition elsewhere or several animations got mixed-up. I 
think I''ve both these potential problems ruled-out.

I can get around this problem quite easily, but it is bugging me that I 
don''t have the slightest clue why my first attempt failed so miserably.

I''ve gone over the Effects.js source, and tried a few adjustments there
but to no effect (pun intended)...

I hardly run Firefox without Firebug enabled these days ;)
